Joelle baked 162 shortbreads. She ate 3
q of them and divided the remainder equally among her 4 friends.
- Find the number of shortbreads each of her friends received in terms of q?
- If q = 14, how many shortbreads did each of her friends receive?
(a)
Number of shortbreads left after Joelle ate = 162 - 3
qNumber of shortbreads that each of her friends received =
162 - 3q4 (b)
Number of shortbreads that each of her friends received
= (162 - (3 x 14)) ÷ 4
= (162 - 42) ÷ 4
= 120 ÷ 4
= 30
Answer(s): (a)
162 - 3q4; (b) 30
