Lucy baked 334 shortbreads. She ate 2
j of them and divided the remainder equally among her 4 friends.
- Find the number of shortbreads each of her friends received in terms of j?
- If j = 19, how many shortbreads did each of her friends receive?
(a)
Number of shortbreads left after Lucy ate = 334 - 2
jNumber of shortbreads that each of her friends received =
334 - 2j4 (b)
Number of shortbreads that each of her friends received
= (334 - (2 x 19)) ÷ 4
= (334 - 38) ÷ 4
= 296 ÷ 4
= 74
Answer(s): (a)
334 - 2j4; (b) 74
