Answer

The total minutes that Jim spent last month = 1102 minutes

Step-by-step explanation

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.

Let the number of minutes that Jim used that was above the first 1000 minutes be x.

Jim's total charge for using an extra x minutes above the first 1000 minutes will be = (75 + 0.30x) dollars.

This total charge was given as $105.60

75 + 0.30x = 105.60

Subtract 75 from both sides

75 + 0.30x - 75 = 105.60 - 75

0.30x = 30.6

Divide both sides by 0.30

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

x = 102 minutes.

This means that Jim spent an extra 102 minutes above the first 1000 minutes.

So, the total minutes that Jim spent last month = 1000 + 102 = 1102 minutes.

Hope this Helps!!!
