55 more |
Before |
10 u |
5x2 + 55 =
10 u + 55 |
Change |
- 7 u |
- 2x2 - 22 =
- 4 u - 22
|
After |
3 u |
3x2 + 33 =
6 u + 33 |
Comparing biscuits
and muffins in the end |

69 more |
0.7 =
710 25 x 55 = 22
Number of muffins that Aunt Elyse gave to Emily = 4 u + 22
If Aunt Elyse made another 69 biscuits in the end, the number of biscuits and muffins in the end would be the same.
6 u + 33 = 3 u + 69
6 u - 3 u = 69 - 33
3 u = 36
1 u = 36 ÷ 3 = 12
Number of biscuits that Aunt Elyse made
= 10 u
= 10 x 12
= 120
Answer(s): 120
