and macarons at first |

60 more |
Before |
10 u |
5x2 + 60 =
10 u + 60 |
Change |
- 9 u |
- 3x2 - 36 =
- 6 u - 36
|
After |
1 u |
2x2 + 24 =
4 u + 24 |
Comparing muffins
and macarons in the end |
|
42 more |
0.9 =
910 35 x 60 = 36
Number of macarons that Aunt Cindy gave to Natalie = 6 u + 36
If Aunt Cindy made another 42 muffins in the end, the number of muffins and macarons in the end would be the same.
4 u + 24 = 1 u + 42
4 u - 1 u = 42 - 24
3 u = 18
1 u = 18 ÷ 3 = 6
Number of muffins that Aunt Cindy made
= 10 u
= 10 x 6
= 60
Answer(s): 60
