Mortimer wants a dozen doughnuts. He is very cheap and likes to save even the smallest amount of money. He found a coupon in the paper for Dunkin' Donuts. The coupon was for $1 off a dozen. The unit price is $0.35 per donut (before using the coupon). If he doesn’t use the coupon he can get $3.99 a dozen. What do you think Mortimer will do and why?
Answer: He will use the coupon and pay $.35 each. That would be $4.20 - $1 = $3.20 instead of $3.99.
