|
After |
3 u |
+ 444 |
7x2 = 14 u |
|
296 ÷ 2 = 148
3 x 148 = 444
5 x 148 = 740
Total amount that Flynn and Peter had at first
= 5 u + 740 + 16 u
= 21 u + 740
21 u + 740 = 1160
21 u = 1160 - 740
21 u = 420
1 u = 420 ÷ 21 = 20
Amount that Flynn had at first
= 5 u + 740
= 5 x 20 + 740
= 100 + 740
= $840
Answer(s): $840
