Write a system of equations to model situation

Question

Terri's telephone- operating fee 29.95 charge per minute 0.14

Carries connection- operating fee 4.95 charge per minute 0.39

Write a system of equations

Define variables

Answer 1

If we let y = total charges for each girl's phone service, and x = the number of minutes, then we have these two equations:

 

y = 29.95 + 0.14x

 

y = 4.95 + 0.39x
