r of them and divided the remainder equally among her 6 friends.
- Find the number of puffs each of her friends received in terms of r?
- If r = 19, how many puffs did each of her friends receive?
(a)
Number of puffs left after Tiffany ate = 160 - 4
rNumber of puffs that each of her friends received =
160 - 4r6 (b)
