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

[tex]2.50k+5.50\leq 20.00[/tex]

solve for k

subtract 5.50 both sides

[tex]2.50k\leq 20.00-5.50[/tex]

[tex]2.50k\leq 14.50[/tex]

divide by 2.50 both sides

[tex]k\leq 5.8\ games[/tex]

therefore

The greatest number of games Rosa can buy is 5
