3 u + 68 |
8 u + 55 |

8 u |

Amount that Cody had spent
= 68 - 13
= $55
Total amount that Justin and Cody had at first
= 3 u + 68 + 8 u + 55
= 11 u + 123
11 u + 123 = 200
11 u = 200 - 123
11 u = 77
1 u = 77 ÷ 11 = 7
Amount that Justin had at first
= 8 u + 68
= 8 x 7 + 68
= 56 + 68
= $124
Answer(s): $124
