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

Answer:

The greatest number of games Rosa can buy is 5

Step-by-step 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
