Let x = the fixed fee and y = the hourly rate.
For the 2-hour call, you can write:
...and for the 4.5-hour call, you can write:
You need to solve this system of equations for x, the fixed fee.
Solve equation 1) for y and substitute into equation 2) then solve it for x.
Simplify and solve for x. Multiply both sides by 2.
The fixed fee is $25.00
The hourly fee is:
Substitute x = 25.
The hourly fee is $16.00
