100 more |
Before |
10 u |
5x2 + 100 =
10 u + 100 |
Change |
- 9 u |
- 2x2 - 40 =
- 4 u - 40

After |
1 u |
3x2 + 60 =
6 u + 60 |

95 more |
0.9 =
910 25 x 100 = 40
Number of scones that Aunt Vanessa gave to Kathy = 4 u + 40
If Aunt Vanessa made another 95 muffins in the end, the number of muffins and scones in the end would be the same.
6 u + 60 = 1 u + 95
6 u - 1 u = 95 - 60
5 u = 35
1 u = 35 ÷ 5 = 7
Number of muffins that Aunt Vanessa made
= 10 u
= 10 x 7
= 70
Answer(s): 70
