Question

Annabeth has $29.00 to spend at the sporting goods store. She buys a T-shirt that costs $15.32. She also wants to buy a soccer ball for $12.87, a baseball cap for $8.39, a set of shin guards for $14.98, or a water bottle for $5.93. Use the equation $15.32 + c = $29.00, where c is the item's cost, to find the most expensive item Annabeth can buy.

Answer 1

The most expensive she can buy is the soccerball

Explanation:

Given

`Total =\$29.00`

`T\ Shirt = \$15.32`

`Soccer\ Ball= \$12.87`

`Baseball\ Cap = \$8.39`

`Shin\ Guards = \$14.98`

`Water\ Bottle = \$5.93`

Required

Using
`\$15.32 + c = \$29.00`, what is the most expensive she can buy?

`\$15.32 + c = \$29.00`

Subtract $15.32 from both sides

`\$15.32 - \$15.32 + c = \$29.00 - \$15.32`

`\$15.32 - \$15.32 + c = \$13.68`

`c = \$13.68`

This means that she can not afford items that cost more than $13.68

i.e. the shin guards which costs $14.98

The items she can afford and their prices are:

`Soccer\ Ball= \$12.87`

`Baseball\ Cap = \$8.39`

`Water\ Bottle = \$5.93`

The most expensive of them all is:

`Soccer\ Ball= \$12.87`
