After |
5 u |
+ 155 |
2x4 =
8 u |
|
124 ÷ 4 = 31
5 x 31 = 155
9 x 31 = 279
Total amount that Jenson and Elijah had at first
= 9 u + 279 + 12 u
= 21 u + 279
21 u + 279 = 846
21 u = 846 - 279
21 u = 567
1 u = 567 ÷ 21 = 27
Amount that Jenson had left
= 5 u + 155
= 5 x 27 + 155
= 135 + 155
= $290
Answer(s): $290
