40 more |
Before |
10 u |
5x2 + 40 =
10 u + 40 |
Change |
- 9 u |
- 3x2 - 24 =
- 6 u - 24
|
After |
1 u |
2x2 + 16 =
4 u + 16 |
Comparing tarts
and wafers in the end |
|
43 more |
0.9 =
910 35 x 40 = 24
Number of wafers that Aunt Nicole gave to Sabrina = 6 u + 24
If Aunt Nicole made another 43 tarts in the end, the number of tarts and wafers in the end would be the same.
4 u + 16 = 1 u + 43
4 u - 1 u = 43 - 16
3 u = 27
1 u = 27 ÷ 3 = 9
Number of tarts that Aunt Nicole made
= 10 u
= 10 x 9
= 90
Answer(s): 90
