4 u |
3x3 =
9 u |
$143 |
Change |
- 1 u |
- 2x3 =
- 6 u |
|
After |
3 u |
1x3 =
3 u |

The amount that Xylia and Luis each had in the end is the same. Make the amount that each had in the end the same. LCM of 3 and 1 is 3.
Total amount that Xylia and Luis had at first
= 4 u + 9 u
= 13 u
13 u = 143
1 u = 143 ÷ 13 = 11
Total amount that Xylia and Luis spent
= 1 u + 6 u
= 7 u
= 7 x 11
= $77
Answer(s): $77
