Jade bought an equal number of strawberry puffs and banana puffs. She paid $28.50 more for the banana puffs and the strawberry puffs.
- How many puffs did she buy?
- How much did she spend altogether?
(a)
Jade bought an equal number of strawberry puffs and banana puffs. Make the number of strawberry puffs and banana puffs the same. LCM of 6 and 4 is 12.
Number of sets of 6 in 12
= 12 ÷ 6
= 2
Cost of 1 set of 12 strawberry puffs
= 2 x 2.60
= $5.20
Number of sets of 4 in 12
= 12 ÷ 4
= 3
Cost of 1 set of 12 banana puffs
= 3 x 4.90
= $14.70
Amount that Jade paid more for 1 set of 12 banana puffs than 1 set of 12 strawberry puffs
= 14.70 - 5.20
= $9.50
Number of sets of $9.50
= 28.50 ÷ 9.50
= 3
Total number of puffs in 1 set of 12 banana puffs and 12 strawberry puffs
= 2 x 12
= 24
Number of puffs that Jade bought
= 3 x 24
= 72
(b)
Cost of puffs in 1 set of 12 banana puffs and 12 strawberry puffs
= 5.20 + 14.70
= $19.90
Total amount that Jade spent altogether
= 3 x 19.90
= $59.70
Answer(s): (a) 72 ; (b) $59.70
