5 u |
6 u |
Savings that Daniel had last month = 1 u
Savings that Xuan had last month = 1 u
Savings that Daniel has this month = 1 u
Savings that Xuan has this month = 5 u
Amount that Xuan saves this month
= 5 u - 1 u
= 4 u
4 u = 1600
1 u = 1600 ÷ 4 = 400
Total savings that Daniel and Xuan have now
= 5 u + 1 u
= 6 u
= 6 x 400
= $2400
Answer(s): $2400
