E. (2.50 + 0.50m) (3,500-250m)

Step-by-step explanation:

Starting at a base price of 2.50, we then add. 50 per increases in price. (2.50 + 0.50m)

Then we multiply the cost (above) by each sale. Subtracting the decrease in sales per price increase. (3,500-250m)

This results in the expression (2.50+0.50m) (3,500-250m)
