Question

Carlos needs to save an additional $565 before he can purchase a car for his son he plans to save $25 each week at this rate at the end of how many full weeks will he have enough money to purchase the car

Answer 1

Given:

Savings for each week = $25

Amount required before Carlos purchase a car = $565

To find:

The number of full weeks in which he will have enough money to purchase the car.

Solution:

Let the required number of weeks be x.

Savings for 1 week = $25

Savings for x week = $25x

Savings must be greater than equal to $565 to purchase the car.

`25x\geq 565`

Divide both sides by 25.

`x\geq (565)/(25)`

`x\geq 22.6`

So, the smallest possible integer value of x is 23.

Therefore, 23 week are required to have enough money to purchase the car.
