Lee |
Total |
Before |
3 u |
4x2 = 8 u |
$110 |
Change |
- 1 u |
- 3x2 = - 6 u |
|
After |
2 u |
1x2 = 2 u |
|
The amount that Jen 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 Jen and Lee had at first
= 3 u + 8 u
= 11 u
11 u = 110
1 u = 110 ÷ 11 = 10
Total amount that Jen and Lee spent
= 1 u + 6 u
= 7 u
= 7 x 10
= $70
Answer(s): $70
