Question

Mrs. Smith's class is selling frozen pizzas to earn money for a field trip. For every pizza sold, the class makes $5.35. They have already earned $182.90 toward their $750 goal. How many more pizzas must they sell to earn $750? Solve this problem by using an algebraic approach 

Answer 1

Let's say they have to sell x more pizzas to earn $750. They have already earned $182.90, so we'll just subtract this amount from the $750 to figure out how much more money they need to earn:

 

Amt left to raise= 750 - 182.90 = 567.10

 

We know that for every pizza sold, the class makes $5.35. This means that if we multiply 5.35 by x, the number of pizzas they must sell to earn the difference, we will get 567.10:

 

5.35x= 567.10

x = 567.10/ 5.35= 106
