f of them and divided the remainder equally among her 4 friends.
- Find the number of macarons each of her friends received in terms of f?
- If f = 13, how many macarons did each of her friends receive?
(a)
Number of macarons left after Cathy ate = 198 - 6
fNumber of macarons that each of her friends received =
198 - 6f4 (b)

= (198 - 78) ÷ 4
= 120 ÷ 4
= 30
Answer(s): (a)
