Your home company charges you by min last month you used 125 minutes and your bill was $37.50. This month you used 175 minutes how much will your home phone bill be this month?
Let's dividey y by x, so y in this case would be 37.5 and x would be 125 minutes. 37.5/125= .3 So the rate is .3, let's now find the charge at 175 minutes. 175×.3=52.5 So it should've cost $52.50 this month.
