Question

Shauna needs to buy 4 new tires and get an oil change for her car. An oil change costs $47.00 and each tire costs the same amount. If she spent a total of $335.00, how much did each tire cost?

Answer 1

$72

Explanation:

Let t = Tires

Let O = Oil change

Given the following data;

Oil change, O = $47

Translating the word problem into an algebraic equation, we have;

4t + O = $335

Rearranging the equation, we have;

`4t = 335 - O`

Substituting the value of O;

`4t = 335 - 47`

`4t = 288`

`t = \frac {288}{4}`

t = 72

Therefore, the cost of each tire is $72.
