Question

Solve. Please show the algebraic inequality you used and show all of your work.
Two cell phone companies are advertising rates. Company A charges a rate of $20 per month plus $0.05 per minute. Company B charges a rate of $10 per month plus $0.10 per minute. What is the number of minutes used above which Company A costs more than Company B?

Answer 1

20 + x(.05)=10 + x(.1)
-10 both sides
10 + x(.05) = x(.1)
- x(.05) both sides
10 = .05x
divide by .05 both sides
x= 200
