Question

Eric orders 3 large cheese pizzas. There is a $2 delivery fee for each pizza. He pays a total of $42. Which equation can be used to find the price, r, of each pizza?

Answer 1

we have that he paid 4 dollars due the delivery. So each pizza costs

$\frac{38}{2}=19$

so the equation to find the price r is

$r=\frac{42-4}{2}$
