6 u |
7 u |
Savings that Billy had last month = 1 u
Savings that Zara had last month = 1 u
Savings that Billy has this month = 1 u
Savings that Zara has this month = 6 u
Amount that Zara saves this month
= 6 u - 1 u
= 5 u
5 u = 650
1 u = 650 ÷ 5 = 130
Total savings that Billy and Zara have now
= 6 u + 1 u
= 7 u
= 7 x 130
= $910
Answer(s): $910
