Half of a pepperoni pizza plus 3/4ths of a ham and pineapple pizza has 765 calories. 1/4th of a pepp

Half of a pepperoni pizza plus 3/4ths of a ham and pineapple pizza has 765 calories. 1/4th of a pepperoni pizza and a whole ham and pineapple pizza contains 745 calories. How many calories are each of the 2 kinds of pizzas individually?

Let p be the pepperoni pizza calories and h be the ham and pineapple pizza calories. We're given

1. 0.5p + 0.75h = 765
2. 0.25p + h = 745

With this system of equations, we can solve using 3 methods:

• Substitution Method
• Elimination Method
• Cramer's Rule

No matter what method we choose, we get:
h = 580
p = 660
