The Great Pizza Deal

Posted on September 23, 2009

The 10" pizza sells for $ 3.99 at my favorite pizza store. The store claims they have a great deal on the large 12" pizza, which is specially priced at $ 4.88. What is the per cent discount the store is offering?

    (10*10)Pi cost=$ 3.99
    1 cost= $ 3.99/(100Pi)
    (12*12)Pi cost=$ 3.99*(144Pi)/(100Pi) =$ 5.7456
    discount= (5.7456-4.88)/5.7456*100 =15.0654%
