Gwen baked 321 tarts. She ate 3
r of them and divided the remainder equally among her 6 friends.
- Find the number of tarts each of her friends received in terms of r?
- If r = 11, how many tarts did each of her friends receive?
(a)
Number of tarts left after Gwen ate = 321 - 3
rNumber of tarts that each of her friends received =
321 - 3r6 (b)
Number of tarts that each of her friends received
= (321 - (3 x 11)) ÷ 6
= (321 - 33) ÷ 6
= 288 ÷ 6
= 48
Answer(s): (a)
321 - 3r6; (b) 48
