Given:
salads : 7 each
drinks: 3 each
delivery charge : 5 per order
budget : 50

The inequality would look like this.

7x + 3y + 5 < 50  

The total cost of the order should be less than or equal to 50.

x = 3

7(3) + 3y + 5 < 50
21 + 3y +  5 < 50
26 + 3y < 50
-26           -26
         3y  < 24
       ÷3       ÷3
            y < 8

The maximum number of drinks Valerie can buy is 8. 

1 order of 3 salads and 8 drinks for a total of 50.
