Question

Jeff ordered 5 pizzas for his daughters birthday party. 60% of the pizzas were eaten at the party. When the party was over, Jeff ate 25% of what was left. If a pizza has 8 slices, how many did Jeff eat?

Answer 1

Jeff ate 4 slices of pizza

Explanation:

First off, let's find how many total slices there are in 5 pizzas.

We know that each pizza has 8 slices, and that Jeff ordered 5 pizzas in total.

Total Slices = 5 pizzas * 8 slices = 40 slices

Let's rewrite the percentages as fractions to make things a little easier:

60% = 6/10

25% = 1/4

Now, lets find out how many slices were left after the party:

`40-((6)/(10) )(40)=16`

Now all we need to do is find 25% or 1/4 of 16:

`16/4 = 4`

Therefore, Jeff ate 4 slices of pizza!
