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

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

112 more |
0.9 =
910 25 x 70 = 28
Number of scones that Aunt Jade gave to Sarah = 4 u + 28
If Aunt Jade made another 112 macarons in the end, the number of macarons and scones in the end would be the same.
6 u + 42 = 1 u + 112
6 u - 1 u = 112 - 42
5 u = 70
1 u = 70 ÷ 5 = 14
Number of macarons that Aunt Jade made
= 10 u
= 10 x 14
= 140
Answer(s): 140
