Question 1

A school fundraiser sold 240 tickets. Adult tickets cost $5 and children's tickets cost $3. If $960 was collected, how many adult tickets were sold?

Accepted Answer

120

Answer

Let a = adult tickets; 5a + 3(240−a) = 960 → 2a = 240 → a = 120.

Question 2

What is 40% of 3/4?

Accepted Answer

10 × $0.25 + 8 × $0.10 + 6 × $0.05 = $2.50 + $0.80 + $0.30 = $3.60.

Question 4

If 3 workers can complete a job in 12 days, how many days would it take 9 workers to complete the same job?
