| After |
1 u |
6 u |
7 u |
Savings that Ryan had last month = 1 u
Savings that Xuan had last month = 1 u
Savings that Ryan has this month = 1 u
Savings that Xuan has this month = 6 u
Amount that Xuan saves this month
= 6 u - 1 u
= 5 u
5 u = 600
1 u = 600 ÷ 5 = 120
Total savings that Ryan and Xuan have now
= 6 u + 1 u
= 7 u
= 7 x 120
= $840
Answer(s): $840
