Sabrina baked 188 shortbreads. She ate 4
z of them and divided the remainder equally among her 5 friends.
- Find the number of shortbreads each of her friends received in terms of z?
- If z = 12, how many shortbreads did each of her friends receive?
(a)
Number of shortbreads left after Sabrina ate = 188 - 4
zNumber of shortbreads that each of her friends received =
188 - 4z5 (b)
Number of shortbreads that each of her friends received
= (188 - (4 x 12)) ÷ 5
= (188 - 48) ÷ 5
= 140 ÷ 5
= 28
Answer(s): (a)
188 - 4z5; (b) 28
