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

He used a total of 1102 minutes.

105.60 - 75 = 30.60

30.60/0.30 = 102

102+1000= 1102

Answer 2

1102 minutes.

Explanation:

Let x represent number of minutes beyond the first 1000 minutes.

We have been given that Jim pays $75 per month for a cell phone plan plus $0.30 per minute beyond the first 1000 minutes.

The cost of minutes beyond the first 1000 minutes would be
`0.30x`.

The total cost of Henry's bill would be
`0.30x+75`.

`0.30x+75=105.60`

`0.30x+75-75=105.60-75`

`0.30x=30.6`

`(0.30x)/(0.30)=(30.6)/(0.30)`

`x=102`

The total minutes used by Jim will be 102 plus 1000.

`1000+102=1102`

Therefore, Jim used 1102 minutes.
