So, 500 cents in dollars are- 500/100 = $5. So, he makes $5 for delivering 50 mails. Answer: A. $5 Question 6: Step 1: Edward Cullen charges $10 per hour washing cars. He washes cars for 6 hours a week. Then, in 5 weeks, he works for 6 * 5 = 30 hours. Step 2: The money he makes by working 30 hours is 30 * $10 = $300. So, he will earn $300 in five weeks.

Question 12: Step 1: Alvin has 213 coins, Simon has 35 more coins than Alvin, and Theodore has 42 fewer coins than Simon. Then, Simon has 213 + 35 = 248 coins. Theodore has 248 - 42 = 206 coins. Step 2: So, the amount Theodore has in his pockets is 206 * 10 = 2,060 cents. We know that- $1 = 100 cents. So, 2,060 cents = 2,060/100 = $20.60. Answer: A. $20.60 Question 13: Step 1: It took the Mystery Machine six hours, driving at 45 kilometres per hour, to travel from Riverdale to Greendale. The distance between Riverdale and Greendale is 45 km/hr * 6 hr = 270 km. Step 2: The Mystery Machine consumed half a litre of petrol per kilometre. Then, the total amount of petrol consumed by the machine was- 1/2 lt/km * 270 km = 135 litres. The cost of petrol was $8/litre. Then, the amount spent on petrol to travel from Riverdale to Greendale was- 135 * $8 = $1,080. Answer: D. $1,080 Question 14: Step 1: William had $20 when he went to the mall. He spent 80% of the amount. Then, the amount spent by him was 0.80 * $20 = $16. Step 2: Then, the amount he was left with is $20 - $16 = $4. Answer: B. $4 ©Scholarly 2025. All rights reserved.
