The 8" pizza sells for $ 4.99 at my favorite pizza store. The store claims they have a great deal on the large 14" pizza, which is specially priced at $ 11.5. What is the per cent discount the store is offering?

Lets solve this question by cost per unit area.
First, for the 8" pizza, the area is pi x 4^2 = 50.26
For the 14" pizza, the area is pi x 7^2 = 153.9
So, now we know that 50.26 unit^2 of pizza would cost us $4.99.
By ratio, 153.9 unit^2 of pizza would cost $15.27
So the 14" pizza is at a discounted price of:
11.5/15.27 x 100% = 75.31%
So the store is offer a discount of 24.69%.
