Rosa wants to use $20 to buy games. The

inequality 2.50k + 5.50 < 20.00 represents the

number of games, k, she can buy with her money.

What is the greatest number of games Rosa can

buy?

A. 5

B.

6

C. 8

D.

10

The answer is B : 6

Step-by-step explanation:

2.50k means 2.50 multiplied by a number and the inequality means 20 is less than 2.50k + 5.50. 2.50 multiplied by 6 equals 15 and 15 plus 5.50 is 20.50 which is greater than 20.
