Pepperoni...mushrooms...ham and pineapple… No matter what your preferred toppings, I think we can all agree that sometimes pizza is a necessity! On those days when you just need a slice (or two, or eight) of pizza, your math skills will help you figure out how to get it. This week’s word problem challenge illustrates that point by asking students to use their elementary math skills such as addition, subtraction, fractions, and conversion from gallons to cups to help a family get to a pizza restaurant.

See if you can solve this week’s challenge. Take your time determining your answer, then look below to check your solution with ours.

Challenge: A family drives 4 miles to get to a pizza restaurant. Their car can travel 32 miles per gallon of gasoline. How many cups of gasoline does it take to get to the pizza restaurant?
(Hint: There are 16 cups in a gallon.)

Solution: Since the car can travel 32 miles per gallon of gasoline, 1 mile takes 1/32 of a gallon and 4 miles takes 4/32 = ⅛ of a gallon. A gallon is the same as 16 cups, so ⅛ of a gallon is ⅛ of 16 cups, which is 2 cups. So, it takes 2 cups of gasoline to get to the pizza restaurant.

Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
