|
After |
5 u |
+ 325 |
5x4 =
20 u |
|
260 ÷ 4 = 65
5 x 65 = 325
9 x 65 = 585
Total amount that Vincent and Carl had at first
= 9 u + 585 + 24 u
= 33 u + 585
33 u + 585 = 1740
33 u = 1740 - 585
33 u = 1155
1 u = 1155 ÷ 33 = 35
Amount that Vincent had left
= 5 u + 325
= 5 x 35 + 325
= 175 + 325
= $500
Answer(s): $500
