| Before |
3 u + 50 |
7 u + 2 |

| Change |
- 50 |
- 2 |

7 u |

Amount that Brandon had spent
= 50 - 48
= $2
Total amount that Ahmad and Brandon had at first
= 3 u + 50 + 7 u + 2
= 10 u + 52
10 u + 52 = 142
10 u = 142 - 52
10 u = 90
1 u = 90 ÷ 10 = 9
Amount that Ahmad had at first
= 7 u + 50
= 7 x 9 + 50
= 63 + 50
= $113
Answer(s): $113
