and macarons at first |

65 more |
Before |
10 u |
5x2 + 65 =
10 u + 65 |
Change |
- 7 u |
- 2x2 - 26 =
- 4 u - 26
|
After |
3 u |
3x2 + 39 =
6 u + 39 |
Comparing muffins
and macarons in the end |
|
87 more |
0.7 =
710 25 x 65 = 26
Number of macarons that Aunt Erika gave to Lynn = 4 u + 26
If Aunt Erika made another 87 muffins in the end, the number of muffins and macarons in the end would be the same.
6 u + 39 = 3 u + 87
6 u - 3 u = 87 - 39
3 u = 48
1 u = 48 ÷ 3 = 16
Number of muffins that Aunt Erika made
= 10 u
= 10 x 16
= 160
Answer(s): 160
