monthly plans plan a cost $13 plus an additional $.14 for each minute of calls
let the number of minutes be x, and the total be y
y= 13+0.14x--------------------1
Plan B cost $18 plus an additional of $.09 for each minute of calls
let the number of minutes be x, and the total be y
y= 18+0.09x--------------------2
Step two:
Equate 1 and 2 above
13+0.14x=18+0.09x
collect like terms
18-13= 0.14x-0.09x
5=0.05x
divide both sides by 0.05
x=5/0.05
x=100 minutes
