Answer:

14 sets

Step-by-step explanation:

Let the number of big screen TV sets be---------x

Portable TV screen sets will be-------x + 40

Console TV sets will be---------- x + 15

The total cost of storage per month is : $302

The equation for total cost is;

7.50 x + 4{ x+15} + 1.50 { x+40 } = 302

7.50x + 4x + 60 + 1.50 x + 60 =302

13x = 302- 120

13x = 182

x = 14
