| Before |
3 u + 64 |
4 u + 38 |

3 u |
4 u |

Amount that Cody had spent
= 64 - 26
= $38
Total amount that Ian and Cody had at first
= 3 u + 64 + 4 u + 38
= 7 u + 102
7 u + 102 = 109
7 u = 109 - 102
7 u = 7
1 u = 7 ÷ 7 = 1
Amount that Ian had at first
= 4 u + 64
= 4 x 1 + 64
= 4 + 64
= $68
Answer(s): $68
