Question

Maria plans to rent a boat. The boat rental costs $60 per hour, and she will also have to pay for a water safety course that costs $10. Maria wants to spend no more than $280 for the rental and the course. If the boat rental is available only for a whole number of hours, what is the maximum number of hours for which Maria can rent the boat?

Answer 1

Hello
My answer is: ⬆

Answer 2

Given:

Rental cost of the boat = $60 per hour,

Cost of the safety course = $10

Amount not to be exceeded =  $280

To Find:

The maximum number of hours for which Maria can rent the boat?

Solution:

Let the cost be = x

Therefore,

The boat is rented at $60 per hour, thus cost to rent a boat will be = 60x ( hours)

She wants to spend not more than $280, thus, =  ≤ 280

The maximum number of hours for which she can rent the boat will be -

= 60x + 10 ≤ 280

= 60x ≤ 280 - 10

= x ≤ 270/60

= 4.5

= 4 ( Because the boat may only be hired for whole numbers of hours, Maria can only rent it for a maximum of four hours.

Answer: Maximum number of hours for which Maria can rent the boat is 4.
