3 u |
4 u |
Savings that Owen had last month = 1 u
Savings that Jean had last month = 1 u
Savings that Owen has this month = 1 u
Savings that Jean has this month = 3 u
Amount that Jean saves this month
= 3 u - 1 u
= 2 u
2 u = 720
1 u = 720 ÷ 2 = 360
Total savings that Owen and Jean have now
= 3 u + 1 u
= 4 u
= 4 x 360
= $1440
Answer(s): $1440
