Marion baked 171 puffs. She ate 3
f of them and divided the remainder equally among her 4 friends.
- Find the number of puffs each of her friends received in terms of f?
- If f = 13, how many puffs did each of her friends receive?
(a)
Number of puffs left after Marion ate = 171 - 3
fNumber of puffs that each of her friends received =
171 - 3f4 (b)
Number of puffs that each of her friends received
= (171 - (3 x 13)) ÷ 4
= (171 - 39) ÷ 4
= 132 ÷ 4
= 33
Answer(s): (a)
171 - 3f4; (b) 33
