Problema Solution
Joe has a coupon to buy one large pizza at regular price, and get one large pizza (of equal or lesser value) free. Joe needs to order 18 pizzas for his party. How many pizzas will Joe pay regular price for?*
Answer provided by our tutors
it depends on the terms of the coupon... if the coupon is good for an unlimited number of pizzas, then Joe buys one and gets one free 9 times, therefore paying regular price for 9 pizzas... however, if the coupon is only good for 1 purchase, Joe gets one pizza free and has to pay regular price for 17 pizzas
...therefore, the problem statement provides insufficient information
