Question

Mrs.Canales 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 seel to earn $750? Slove this propblem first by using an arithmetic approch then bye an agebraic approch.Compare the calculations you made using each approch

Answer 1

The amount of money that they still have to earn in order to achieve their goal is the difference between $750 (goal) and $182.90 (current earnings) which is equal to $567.1. To determine the number of pizzas that still have to be sold, we divide this amount by the unit price of pizza. 
                               n = $567.1 / $5.35 = 106
Therefore, Mrs. Canales' class should be able to sell another 106 pizzas.
