Question

Over the last 9 tuesdays,Ms. Chan has gotten 3 coupons good for a free sandwich. Suppose Ms. Chan goes to the deli 36 tuesdays in the next year. How many free sandwiches can she expect to win based on her experience so far?

Answer 1

Every 9 Tuesdays got 3 free sandwhiches, so 36 Tuesdays ÷ 9= 4× 3 = 12

Answer 2

Well for every 9 Tuesday’s that she goes, she gets 3, so since 9•4 equals 36, then to solve you multiply 3 times 4, equals 12, so she will most likely get 12 coupons in the next year
