Trevor's dad decided to get him a cell phone for his birthday. Cell Plus has a plan that costs $20.00 per month plus an additional $0.06 per minute. Cell Best has a plan that costs $30.00 per month plus an additional $0.05 per minute. How many minutes can Trevor talk and both cell plans cost the same amount?

    If x is the number of minutes talked then the Cell Plus plan would cost \[20.00+0.06x\]How would you express the Cell Best plan?

    Cell Best is the name of the 2nd company. We are looking for the amount of time he can talk where the total cost (TC) of both plans would be the same. If the total cost of the Cell Plus plan is given by 20.00 + 0.06x = TC The total cost of the Cell Best plan would be given by 30.00 + 0.05x =TC Do you see how I developed these expressions?

    The two total costs have to be equal so set the equations equal to each other.
