3 u |
4 u |
Savings that Eric had last month = 1 u
Savings that Yoko had last month = 1 u
Savings that Eric has this month = 1 u
Savings that Yoko has this month = 3 u
Amount that Yoko saves this month
= 3 u - 1 u
= 2 u
2 u = 380
1 u = 380 ÷ 2 = 190
Total savings that Eric and Yoko have now
= 3 u + 1 u
= 4 u
= 4 x 190
= $760
Answer(s): $760
