Erika baked 217 puffs. She ate 2
b of them and divided the remainder equally among her 5 friends.
- Find the number of puffs each of her friends received in terms of b?
- If b = 16, how many puffs did each of her friends receive?
(a)
Number of puffs left after Erika ate = 217 - 2
bNumber of puffs that each of her friends received =
217 - 2b5 (b)
Number of puffs that each of her friends received
= (217 - (2 x 16)) ÷ 5
= (217 - 32) ÷ 5
= 185 ÷ 5
= 37
Answer(s): (a)
