Elyse baked 221 wafers. She ate 3
b of them and divided the remainder equally among her 5 friends.
- Find the number of wafers each of her friends received in terms of b?
- If b = 12, how many wafers did each of her friends receive?
(a)
Number of wafers left after Elyse ate = 221 - 3
bNumber of wafers that each of her friends received =
221 - 3b5 (b)
Number of wafers that each of her friends received
= (221 - (3 x 12)) ÷ 5
= (221 - 36) ÷ 5
= 185 ÷ 5
= 37
Answer(s): (a)
221 - 3b5; (b) 37
