Question

Jim pays $75 per month for a cell phone plan plus $0.30 per minute beyond the first 1000 minutes. His bill was $105.60 last month. How many minutes did he use?

Answer 1

1102 minutes

Explanation:

Easy way to do it: 1000 + 102 = 1102

Step by step

1: 105.60=75+0.30(x-1000)

2: 105.60 =75+0.30x−300

3: 105.60=0.30x−225

4: 1056=3x−2250

5: 1056+2250=3x

6: 3306=3x

7: x=1102

Hope this helps.
