Natalie spent $98 to buy some boxes of apple and strawberry puffs. Each box of apple puffs cost $8 and each box of strawberry puffs cost $11. The apple puffs were packed in boxes of 12 puffs each and the strawberry puffs were packed in boxes of 8 puffs each. She bought an equal number of apple puffs and strawberry puffs.
(a) How many boxes of apple puffs did she buy?
(b) How many boxes of strawberry puffs did she buy?
(a)
Total number of apple puffs and strawberry puffs is the same.

LCM of 12 and 8 = 24

Number of boxes for 24 apple puffs
= 24 ÷ 12
= 2

Number of boxes for 24 strawberry puffs
= 24 ÷ 8
= 3

1 set = 2 boxes of apple puffs and 3 boxes of strawberry puffs

Cost of 1 set
= 2 x 8 + 3 x 11
= 16 + 33
= $49

Number of sets
= 98 ÷ 49
= 2

Boxes of apple puffs
= 2 x 2
= 4

(b)
Boxes of strawberry puffs
= 2 x 3
= 6

Answer(s): (a) 4; (b) 6
