85 more |
Before |
10 u |
5x2 + 85 =
10 u + 85 |
Change |
- 9 u |
- 2x2 - 34 =
- 4 u - 34
|
After |
1 u |
3x2 + 51 =
6 u + 51 |
Comparing muffins
and tarts in the end |
|
151 more |
0.9 =
910 25 x 85 = 34
Number of tarts that Aunt Jane gave to Betty = 4 u + 34
If Aunt Jane made another 151 muffins in the end, the number of muffins and tarts in the end would be the same.
6 u + 51 = 1 u + 151
6 u - 1 u = 151 - 51
5 u = 100
1 u = 100 ÷ 5 = 20
Number of muffins that Aunt Jane made
= 10 u
= 10 x 20
= 200
Answer(s): 200
