Question

It costs $2.00 per hour to park in the parking deck. Ben parks for 3 hours. The automated machine used for payment will only accept quarters. How many quarters does Ben need to exit the deck?

Answer 1

Answer: Bn would pay 24 quarters to exit the deck

Explanation:

The cost of parking in the parking deck per hour is $2. This means that the cost of parking for x hours would be $2x.

Ben parks for 3 hours. The total amount that he would pay is

3 × 2 = $6

The automated machine used for payment will only accept quarters. A quarter is worth 25 cents. Converting 25 cents to dollars, it becomes

25/100 = $0.25

Therefore, the number of quarters that he would pay to exit the deck is

6/0.25 = 24 quarters

Answer 2

the correct answer is 24 quarters

Explanation:

Since Ben parks for 3 hours and one hours costs $2

Therefore 3 hours = $2.00 × 3 hours = $6.00

Next, note that 1 quarter = 25 cents (same as One-quarter of a dollar)

∴ 1 quarter = 1/4 dollar

= 1 quarter = 0.25 dollars.

$0.25 = 1 quarter

∴ $6 = (1/0.25) × 6 = (6 ÷ 0.25) = 24 quarters
