Here's something us guys here at DebtSmart were discussing last week. We're always ordering from this Sub Shop down the street and, being the thrifty folks we are, we decided to figure out the most money-saving way to get lunch. An excellent example of math that can be applied to everyday situations.
 
1.

Every time you order a sub, whether it’s a whole sub or a half-sub you get a coupon. When you accumulate 15 coupons you get a free whole sub. Four (4) of us from work are going out to lunch, everybody is going to order the Cheese, Boiled Ham, Proscuittini, Cappacuolo sandwich which costs $7.45 for a whole sub and $4.70 for a half-sub. Each person eats a half-sub for lunch and we plan on going here all the time.

We’ve already collected 11 coupons. Is it better to get 4 half-subs now and get the free whole sub next time, or is it better to split 2 whole subs this time and next time, and get the free whole sub on the third lunch trip?
Get whole subs
Get half-subs
I don't know!
