1. Large pizzas cost $12.50 and small pizzas cost $9.00. The pizza parlor sold 38 pizzas with a total value of $415.50. How many of each type did the pizza parlor sell?
Answer provided by our tutors
let 'x' represent the number of small pizzas sold, then '38-x' represents the number of large pizzas sold
Sold for the number of small pizzas sold:
415.50 = 9x + 12.5(38-x)
-----------------
-----------------
x=17
38-17 = 21
So 17 small pizzas and 21 large pizzas were sold.
