Mrs. Long wants to rent a bounce house for her owens birthday. Inflate a rentals charges a 145 fee plus 35 per hour. If Mrs. Long paid 355 total, how many hours did she rent the bounce house for

The correct answer is 6 hours.

Step-by-step explanation:

Let Mrs. Long rent the bounce house for x hours.

Fixed price to be charged is 145.

Per hour price of the bounce house is 35. Total price of x hours is 35x.

Thus total amount charged by the rentals is 145 + 35x.

Mrs. Long paid 355 in total.

∴ 145 + 35x = 355

⇒ 35x = 210

⇒ x = 6.

Thus Mrs. Long rented the bounce house for 6 hours.
