and wafers at first |

95 more |
Before |
10 u |
5x2 + 95 =
10 u + 95 |
Change |
- 7 u |
- 2x2 - 38 =
- 4 u - 38
|
After |
3 u |
3x2 + 57 =
6 u + 57 |
Comparing muffins
and wafers in the end |
|
99 more |
0.7 =
710 25 x 95 = 38
Number of wafers that Aunt Gem gave to Natalie = 4 u + 38
If Aunt Gem made another 99 muffins in the end, the number of muffins and wafers in the end would be the same.
6 u + 57 = 3 u + 99
6 u - 3 u = 99 - 57
3 u = 42
1 u = 42 ÷ 3 = 14
Number of muffins that Aunt Gem made
= 10 u
= 10 x 14
= 140
Answer(s): 140
