b of them and divided the remainder equally among her 5 friends.
- Find the number of biscuits each of her friends received in terms of b?
- If b = 17, how many biscuits did each of her friends receive?
(a)
Number of biscuits left after Irene ate = 152 - 6
bNumber of biscuits that each of her friends received =
152 - 6b5 (b)
Number of biscuits that each of her friends received
= (152 - (6 x 17)) ÷ 5
= (152 - 102) ÷ 5
= 50 ÷ 5
= 10
Answer(s): (a)
