Sam |
| Before |
5x7 =
35 u |
7x5 =
35 u |
| Change |
- 4x7 =
- 28 u |
- 3x5 =
- 15 u |
| After |
1x7 =
7 u |
4x5 =
20 u |
The amount that Bryan and Sam each earned in a month is the same. Make the amount the same. LCM of 5 and 7 is 35.
Amount that Bryan saved more than Sam
= 28 u - 15 u
= 13 u
13 u = 100
1 u = 100 ÷ 13 = 100
Amount that Sam saved in a month
= 15 u
= 15 x 100
= $1500
Answer(s): $1500
