Question

You call the pizza store and find out that each pizza has 12 slices. you expect 16 people to come, and you estimate each person will eat 3 slices. How many pizzas should you order?

Now use the formula to solve the problem.
x=number of people at the party
y=number of slices per pizza
z=number of pizzas
n=number of slices each person will eat
nx/y=z

Answer 1

nx/y=z
3(16)/12=z
3x16=48/12=4
z=4
