Answer:
1102 minutes.
Step-by-step 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 [tex]0.30x[/tex].
The total cost of Henry's bill would be [tex]0.30x+75[/tex].
[tex]0.30x+75=105.60[/tex]
[tex]0.30x+75-75=105.60-75[/tex]
[tex]0.30x=30.6[/tex]
[tex]\frac{0.30x}{0.30}=\frac{30.6}{0.30}[/tex]
[tex]x=102[/tex]
The total minutes used by Jim will be 102 plus 1000.
[tex]1000+102=1102[/tex]
Therefore, Jim used 1102 minutes.
