Critical Thinking/Finding Together

The number of slices in the 1st giant pizza is a

prime number between 10 and 20. The number

of slices in the 2nd and 3rd giant pizzas together

is a multiple of 5. If the total number of slices is

32, how many slices are there in the 1st pizza?

You may have thought there was no mathematics

in pizza. Well, there is. It turns out there is mathe-

matics in plain cheese pizzas, sausage pizzas, pepper-

oni pizzas, pineapple pizzas, teriyaki pizzas, and

avocado pizzas, just to name a few. (Sometimes, it’s

just not good to take mathematics too seriously.)
