Emma baked 261 wafers. She ate 3
n of them and divided the remainder equally among her 4 friends.
- Find the number of wafers each of her friends received in terms of n?
- If n = 15, how many wafers did each of her friends receive?
(a)
Number of wafers left after Emma ate = 261 - 3
nNumber of wafers that each of her friends received =
261 - 3n4 (b)
Number of wafers that each of her friends received
= (261 - (3 x 15)) ÷ 4
= (261 - 45) ÷ 4
= 216 ÷ 4
= 54
Answer(s): (a)
261 - 3n4; (b) 54
