After |
7 u + $93.70 |
4 u |
3 u + $93.70 |
Ivan had $151.90 more than Rael in the end.
7 u + 93.70 - 4 u = 151.90
3 u + 93.70 = 151.90
3 u = 151.90 - 93.70
3 u = 58.20
1 u = 58.20 ÷ 3 = 19.40
Amount that Ivan had at first
= 7 u + 93.70
= 7 x 19.40 + 93.70
= 135.80 + 93.70
= $229.50
Answer(s): $229.50
