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?

Since each pizza had 8 slices                       5 • 8 = 40  slices to begin with  

 

At the party 60% were eaten                       0.60 • 40 = 24  slices eaten at the party  

 

Since 24 slices were eaten at the party        40 – 24 = 16  slices left over after the party  

 

Jeff ate 25% of the leftover pizza                  0.25 • 16 = 4 slices that Jeff ate after the party
