90 more |
Before |
10 u |
5x2 + 90 =
10 u + 90 |
Change |
- 7 u |
- 2x2 - 36 =
- 4 u - 36
|
After |
3 u |
3x2 + 54 =
6 u + 54 |
Comparing cupcakes
and wafers in the end |
|
108 more |
0.7 =
710 25 x 90 = 36
Number of wafers that Aunt Raeann gave to Hazel = 4 u + 36
If Aunt Raeann made another 108 cupcakes in the end, the number of cupcakes and wafers in the end would be the same.
6 u + 54 = 3 u + 108
6 u - 3 u = 108 - 54
3 u = 54
1 u = 54 ÷ 3 = 18
Number of wafers that Aunt Raeann made
= 10 u + 90
= 10 x 18 + 90
= 180 + 90
= 270
Answer(s): 270
