Answer:
They must sell 106 more pizzas to earn $750.
Step-by-step explanation:
We are given that Mrs. Canale class is selling frozen pizzas to earn morning for a field trip. For every pizza sold, the class makes $5.35.
They have already earned $182.90, but they need $750. We have to find that how many more pizzas must they sell to be able to earn $750.
So, Firstly we will find that how much money did they have to earn more to be able to reach at $750.
Since, it is given that they have already earned $182.90.
So, Amount of more money they have to earn to reach at $750 = Final amount - Amount they already have
= $750 - $182.90 = $567.1
That means they have to earn $567.1 more to be able to reach at $750 mark.
Also, it is known that the price of every pizza sold = $5.35
So, Number of pizza that should be sold to earn an amount of $567.1 is given by;
Number of pizzas = [tex]\frac{567.1}{5.35}[/tex] = [tex]\frac{5670}{535}[/tex] = 106
Therefore, Mrs. Canale class must sell 106 more pizzas to be able to earn a total amount of $750.
