Barbara baked 379 puffs. She ate 5
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 = 15, how many puffs did each of her friends receive?
(a)
Number of puffs left after Barbara ate = 379 - 5
fNumber of puffs that each of her friends received =
379 - 5f4 (b)
Number of puffs that each of her friends received
= (379 - (5 x 15)) ÷ 4
= (379 - 75) ÷ 4
= 304 ÷ 4
= 76
Answer(s): (a)
379 - 5f4; (b) 76
