Question

rosa wants to use $20 to buy games. The inequality 2.50k+5.50≤20.00 represent the number of games, k, she can buy with her money. What is the greatest number of games Rosa can buy?

Answer 1

The greatest number of games Rosa can buy is 5

Explanation:

Let

k ----> the number of games, k, that Rosa can buy with her money

we have

`2.50k+5.50\leq 20.00`

solve for k

subtract 5.50 both sides

`2.50k\leq 20.00-5.50`

`2.50k\leq 14.50`

divide by 2.50 both sides

`k\leq 5.8\ games`

therefore

The greatest number of games Rosa can buy is 5
