Question

Carl rented a bounce house for his little brother's birthday party. The company charges a base rental charge of $95.25, plus a certain amount per hour. Carl's little brother's party lasted 4 hours, and costs $179.72. Carl plans to rent a bounce house for his little sister's birthday party for 6 hours for about $200. Is this a reasonable estimate? A. Yes, the estimate is reasonable. B. No, the estimate should be lower. C. No, the estimate should be higher.

Answer 1

C. No, the estimate should be higher.

Explanation:

Carl's brother party

Fixed charge = $95.25

Number of hours = 4 hours

Hourly charge = x

Total cost = $179.72

179.72 = 95.25 + 4x

179.72 - 95.25 = 4x

84.47 = 4x

x = 84.47/4

x = 21.1175

Hourly charge = $21.1175

Carl's little sister party

Estimated total charge = $200

Number of hours = 6

Fixed charge = $95.25

Hourly charge = $21.1175

Total charges = 95.25 + 6(21.1175)

= 95.25 + 126.705

= 221.955

Total charges = $221.955

C. No, the estimate should be higher
