What’s is 4/5•5/7 which they are both negative

-20/35    if you simplify it would be -4/7

Step-by-step explanation:

Because the prices are different, you need to use two variables, one for each price.

Let the price for the plain one be X and the price for the printed one be Y.

You would multiply the number of each shirt by the variable:

3 plain would be 3X and 2 printed would be 2Y.

You then need to add those together to get the total cost:

Total cost = 3X + 2Y
