BabaBlast [244]

Answer: 106

Step-by-step explanation:

First, we can subtract 182.90 from 750, and then divide the answer by 5.35.

750 - 182.90 = 567.10. Mrs. Canale's class still needs to earn 567.10 dollars.

Now we can divide 567.10 by 5.35 to find how many frozen pizzas the class has to sell.

567.10 / 5.35 = 106.

Therefore, Mrs. Canale's class will still need to sell 106 frozen pizzas to meet their $750 goal.
