Tiffany baked 312 biscuits. She ate 2
j of them and divided the remainder equally among her 5 friends.
- Find the number of biscuits each of her friends received in terms of j?
- If j = 11, how many biscuits did each of her friends receive?
(a)
Number of biscuits left after Tiffany ate = 312 - 2
jNumber of biscuits that each of her friends received =
312 - 2j5 (b)
Number of biscuits that each of her friends received
= (312 - (2 x 11)) ÷ 5
= (312 - 22) ÷ 5
= 290 ÷ 5
= 58
Answer(s): (a)
312 - 2j5; (b) 58
