1 u |
3 u |
4 u |
Savings that Julian had last month = 1 u
Savings that Esther had last month = 1 u
Savings that Julian has this month = 1 u
Savings that Esther has this month = 3 u
Amount that Esther saves this month
= 3 u - 1 u
= 2 u
2 u = 800
1 u = 800 ÷ 2 = 400
Total savings that Julian and Esther have now
= 3 u + 1 u
= 4 u
= 4 x 400
= $1600
Answer(s): $1600
