Adding additional toppings to a large cheese pizza cost $1.39 per topping. The equation 14.85 + 1.39x = 20 can be used to determine the number of toppings that can be added to a large cheese pizza for a total of $20. Jacob solves the equation and says you can get 4 toppings added if you have $20. Is this reasonable? Justify your response. If the answer is not reasonable, identify the error and then calculate the correct solution.

14.85 + 1.39x = 20

1.39x = 20 – 14.85

1.39x = 5.15

1.39 / 1.39 = 5.15 / 1.39

x = 3.70

Did I answer this correctly, if not can you tell what I did wrong

Thanks!
