Question

15. Pizzas cost $12 each, tax included. You decide to give the delivery driver a $6

tip. Find the cost for 3 pizzas

Answer 1

you would do 12x3 which is 36

Answer 2

Multipy the cost of each pizza to the the number of pizzas you have.
Your equation would look like: y=12x+6

Use 3 for your x value: y= 12(3)+6

y=36+6
y=42.


3 pizzas cost $42
