Anna baked 318 biscuits. She ate 3
x of them and divided the remainder equally among her 5 friends.
- Find the number of biscuits each of her friends received in terms of x?
- If x = 16, how many biscuits did each of her friends receive?
(a)
Number of biscuits left after Anna ate = 318 - 3
xNumber of biscuits that each of her friends received =
318 - 3x5 (b)
Number of biscuits that each of her friends received
= (318 - (3 x 16)) ÷ 5
= (318 - 48) ÷ 5
= 270 ÷ 5
= 54
Answer(s): (a)
318 - 3x5; (b) 54
