Math is everywhere...

Yesterday I was grocery shopping and I noticed a sale on dog food (Normally I would not buy dog food from a grocery store because my mom owns an organic pet food store, but we'll talk more about that latter!)
Purina is on sale for a third off its regular price of $6.00 for 10 weeks. If I bought a bag of dog food once a week for 10 weeks, how much would it cost for 10 bags? How much money would I save? Show your answer as a fraction (multiplication sentence?), and in money.

Beneful is also on sale for 1/4 off it's regular price of $8.00 for 10 weeks. What is the better deal?

I Love Math!
