ORIGINAL SCENARIO — GARDEN GRANT
Three groups share a $1,680 grant. Maple contributed 12 volunteer hours, Birch 18 hours and Cedar 30 hours. Proposal A gives each group an equal share. Proposal B divides the money in proportion to volunteer hours. Unless a question says otherwise, use Proposal B and divide the entire grant. These are fictional allocation rules, not a claim that one rule is always fairest.
How much more does Cedar receive under Proposal B than under Proposal A, using the full grant?
- $224
- $560
- $280
- $840
Show answer and explanation
Correct answer: $280
An equal share is $1,680 ÷ 3 = $560. Cedar’s proportional share is $840, so the difference is $840 − $560 = $280.

Official reference ↗ORIGINAL SCENARIO — REPAIR WORKSHOP
A workshop expects 53 participants. Each rented table seats at most 6 people and costs $18. Hall rental is a fixed $70, and materials cost $3 per participant. The total budget is $450. These fictional prices already include all charges. Each tabletop measures 1.8 m by 0.75 m. The room measures 10 m by 8 m; access routes and safe spacing still need a layout check.
What area do the nine tabletops occupy, excluding all access space?
- 12.15 m²
- 16.20 m²
- 67.85 m²
- 80 m²
Show answer and explanation
Correct answer: 12.15 m²
One tabletop covers 1.8 × 0.75 = 1.35 m². Nine cover 9 × 1.35 = 12.15 m². This excludes chairs, access routes and spacing.

Official reference ↗ORIGINAL SCENARIO — PARK WALK
Organizers expect 800 visitors. In a morning survey, 18 of 60 visitors said they would use a refill station. For planning, assume that the same proportion applies to all 800 visitors and that each user takes one 250 mL serving. Each full cooler holds 18 L. The survey is an estimate, not a promise about attendance or demand.
How much water is needed for one 250 mL serving for each of the estimated users?
- 6 L
- 200 L
- 60 L
- 600 L
Show answer and explanation
Correct answer: 60 L
240 × 250 mL = 60,000 mL. Divide by 1,000 mL per litre to obtain 60 L. The calculation allows exactly one serving per user.
Based on: Original fictional scenario shown above; answer derived from its data and reasoning. B.C. official source describes assessment processes, not this item.
Official reference ↗What is the minimum number of full 18 L coolers needed for the estimated water demand?
- 2
- 3
- 5
- 4
Show answer and explanation
Correct answer: 4
60 ÷ 18 = 3.33… coolers, so round up to 4 whole coolers. Three provide only 54 L; four provide 72 L.

A workshop expects 53 participants. Each rented table seats at most 6 people and costs $18. Hall rental is a fixed $70, and materials cost $3 per participant. The total budget is $450. These fictional prices already include all charges. Each tabletop measures 1.8 m by 0.75 m. The room measures 10 m by 8 m; access routes and safe spacing still need a layout check.
What is the total stated cost for 53 participants using the minimum number of tables?
- $321
- $450
- $391
- $409
Show answer and explanation
Correct answer: $391
Nine tables cost 9 × $18 = $162. Add the $70 hall and 53 × $3 = $159 in materials: $162 + $70 + $159 = $391.

Official reference ↗ORIGINAL SCENARIO — CARGO-BIKE QUOTES
For Service A, the quoted cost is $22 for 2 km, $30 for 4 km and $38 for 6 km. Assume its price follows one linear model. Service B quotes C = 26 + 2d, where C is dollars and d is distance in kilometres. Both fictional quotes include all charges and apply only to trips from 1 km to 12 km. Compare the same trip distance for both services.
Why should a planner not treat the model’s 20 km prediction as a confirmed quote?
- The supplied quotes apply only from 1 to 12 km
- A linear model cannot be used at 9 km
- Service B charges the same price for every distance
- The fixed term must be paid twice at 20 km
Show answer and explanation
Correct answer: The supplied quotes apply only from 1 to 12 km
Twenty kilometres is outside the quoted range. A formula can produce a number there, but the passage does not confirm that either service will charge that price.

Official reference ↗Which fixed term completes Service A’s model C = 4d + b?
- 14
- 18
- 22
- 26
Show answer and explanation
Correct answer: 14
Substitute the 2 km quote: 22 = 4 × 2 + b, so b = 14. The full model is C = 14 + 4d within the stated quote range.

Official reference ↗At what trip distance do the two models give the same price?
- 4 km
- 6 km
- 8 km
- 12 km
Show answer and explanation
Correct answer: 6 km
Set 14 + 4d = 26 + 2d. Then 2d = 12, so d = 6 km. Both services cost $38 at this distance.

For planning, assume that the same proportion applies to all 800 visitors and that each user takes one 250 mL serving. Each full cooler holds 18 L. The survey is an estimate, not a promise about attendance or demand.
If the actual use rate is between 20% and 40%, what range of users should organizers consider?
- 20–40
- 80–160
- 160–320
- 240–400
Show answer and explanation
Correct answer: 160–320
20% of 800 is 160 and 40% of 800 is 320. The range describes users, not litres; water demand must be calculated separately.

Proposal B divides the money in proportion to volunteer hours. Unless a question says otherwise, use Proposal B and divide the entire grant. These are fictional allocation rules, not a claim that one rule is always fairest.
What is Maple’s proportional allocation from the full grant?
- $280
- $560
- $336
- $672
Show answer and explanation
Correct answer: $336
Maple supplied 12/60 = 1/5 of the volunteer hours. Its allocation is $1,680 × 1/5 = $336.

These fictional prices already include all charges. Each tabletop measures 1.8 m by 0.75 m. The room measures 10 m by 8 m; access routes and safe spacing still need a layout check.
If 61 people attend, how does the minimum-table plan compare with the $450 budget?
- $20 under budget
- Exactly on budget
- $18 over budget
- $1 over budget
Show answer and explanation
Correct answer: $1 over budget
61 people need 11 tables. Cost = 11 × $18 + $70 + 61 × $3 = $451, which exceeds the budget by $1. Ten tables would leave one person without a seat.

What percentage of the volunteer hours did Birch contribute?
- 18%
- 25%
- 40%
- 30%
Show answer and explanation
Correct answer: 30%
Birch contributed 18 of the 60 hours: 18 ÷ 60 × 100% = 30%. Its 18 hours are not automatically 18 percent.
