Zoe baked 264 wafers.
58 of the wafers were matcha wafers. The rest were peach wafers. She gave an equal number of matcha wafers and peach wafers away and had 4 times as many matcha wafers as peach wafers left. How many wafers did she give away?

Difference |
| Before |
5x3 =
15 u |
3x3 =
9 u |
2x3 =
6 u |
| Change |
- 7 u |
- 7 u |
|
| After |
4x2 =
8 u |
1x2 =
2 u |
3x2 =
6 u |
Since Zoe gave away an equal number of matcha wafers and peach wafers, the difference in the number of matcha wafers and peach wafers remains unchanged. Make the difference in the matcha wafers and peach wafers the same. LCM of 2 and 3 is 6.
Total number of wafers at first
= 15 u + 9 u
= 24 u
24 u = 264
1 u = 264 ÷ 24 = 11
Number of wafers that Zoe gave away
= 7 u + 7 u
= 14 u
= 14 x 11
= 154
Answer(s): 154
