a of them and divided the remainder equally among her 6 friends.
- Find the number of wafers each of her friends received in terms of a?
- If a = 16, how many wafers did each of her friends receive?
(a)
Number of wafers left after Sarah ate = 284 - 2
aNumber of wafers that each of her friends received =
284 - 2a6 (b)
Number of wafers that each of her friends received
= (284 - (2 x 16)) ÷ 6
= (284 - 32) ÷ 6
= 252 ÷ 6
= 42
Answer(s): (a)
284 - 2a6; (b) 42
