Shannon |
Lee |
Total |
Before |
5 u |
4x2 = 8 u |
$78 |
Change |
- 3 u |
- 3x2 = - 6 u |
|
After |
2 u |
1x2 = 2 u |

The amount that Shannon and Lee each had in the end is the same. Make the amount that each had in the end the same. LCM of 2 and 1 is 2.
Total amount that Shannon and Lee had at first
= 5 u + 8 u
= 13 u
13 u = 78
1 u = 78 ÷ 13 = 6
Total amount that Shannon and Lee spent
= 3 u + 6 u
= 9 u
= 9 x 6
= $54
Answer(s): $54
