Before |
10 u |
5x2 + 70 =
10 u + 70 |
Change |
- 9 u |
- 2x2 - 28 =
- 4 u - 28

After |
1 u |
3x2 + 42 =
6 u + 42 |

137 more |
0.9 =
910 25 x 70 = 28
Number of scones that Aunt Gem gave to Rachel = 4 u + 28
If Aunt Gem made another 137 wafers in the end, the number of wafers and scones in the end would be the same.
6 u + 42 = 1 u + 137
6 u - 1 u = 137 - 42
5 u = 95
1 u = 95 ÷ 5 = 19
Number of scones that Aunt Gem made
= 10 u + 70
= 10 x 19 + 70
= 190 + 70
= 260
Answer(s): 260
