Question

ted talking is trying to decide which cell phone plan will work best for him. Aid plan A charges a $60 monthly fee and 10 cents a minute, while plan B charges $100 monthly fee and 5 cents per minute, how many minutes must Ted talk so the plans would cost the same? Define your variable, write an equation, and solve. Write your answer in a complete sentence!

Answer 1

A: y = 60 + 0.10x
B: y = 100 + 0.05x
y = total cost, x = minutes
60 + 0.10x = 100 + 0.05x
0.10x = 40 + 0.05x
40 = 0.05x
x = 800 minutes
