Below is a piece of a local pizza place menu where jacob works. large cheese pizza $14.85 large supreme pizza $16.90 cheese sticks $5.99 dessert pizza $6.99 5. 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.

It is not reasonable because if someone were to add 4 toppings, the price would be $20.41. However, if a person were to add 3 toppings using that equation, the price would $19.02.

answer: the common difference is -0.10

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
