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?

anonymous · Answer

what do you mean. isnt it asking for how many minutes he can talk.. not the best cell plan

pfenn1 · Answer

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.
