Answer:
For more than 500 minutes
Step-by-step explanation:
Let x be the number of minutes.
First company charges:
$0.029 per minute, then $0.029x for x minutes
and a $2 monthly fee.
In total, $(0.029x+2)
Second company charges:
$0.033 per minute, then $0.033x for x minutes
with no monthly fee.
If the charges for the first company are cheaper, then
[tex]0.029x+2<0.033x[/tex]
Multiply this inequality by 1,000:
[tex]29x+2,000<33x\\ \\33x-29x>2,000\\ \\4x>2,000\\ \\x>500[/tex]
