It is given that a home phone company charges by the minute.
It is given that Last month phone used was 125 minute
And it is also given that Last month bill came = $37.50
Now we have to calculate money charged per minute
Money charged per minute = 37.5 / 125 = $0.3
Now for this month time we have got = 175 minute
So total bill for this month will be =0.3 * 175 = $52.5
