Total |
| Before |
2x4 =
8 u |
3x4 =
12 u |
5x4 =
20 u |
| Change |
- 21 |
+ 21 |
|
| After |
1x5 =
5 u |
3x5 =
15 u |
4x5 =
20 u |
The total amount of money remains the same.
40% =
40100 =
25Amount that Ian gave to Cole
= 8 u - 5 u
= 3 u
3 u = 21
1 u = 21 ÷ 3 = 7
Total amount of money given to the two boys
= 20 u
= 20 x 7
= $140
