|
|
After |
2 u |
+ 122 |
7x3 =
21 u |
|
183 ÷ 3 = 61
2 x 61 = 122
5 x 61 = 305
Total amount that Riordan and Ahmad had at first
= 5 u + 305 + 24 u
= 29 u + 305
29 u + 305 = 914
29 u = 914 - 305
29 u = 609
1 u = 609 ÷ 29 = 21
Amount that Riordan had at first
= 5 u + 305
= 5 x 21 + 305
= 105 + 305
= $410
Answer(s): $410
