Tina baked 80 puffs.
35 of the puffs were matcha puffs. The rest were strawberry puffs. She gave an equal number of matcha puffs and strawberry puffs away and had 3 times as many matcha puffs as strawberry puffs left. How many puffs did she give away?

Matcha puffs |
Strawberry puffs |
Difference |
| Before |
3x2 =
6 u |
2x2 =
4 u |
1x2 =
2 u |
| Change |
- 3 u |
- 3 u |
|
| After |
3x1 =
3 u |
1x1 =
1 u |
2x1 =
2 u |
Since Tina gave away an equal number of matcha puffs and strawberry puffs, the difference in the number of matcha puffs and strawberry puffs remains unchanged. Make the difference in the matcha puffs and strawberry puffs the same. LCM of 1 and 2 is 2.
Total number of puffs at first
= 6 u + 4 u
= 10 u
10 u = 80
1 u = 80 ÷ 10 = 8
Number of puffs that Tina gave away
= 3 u + 3 u
= 6 u
= 6 x 8
= 48
Answer(s): 48
