Kayla wants to have new doors installed.

The door company charges $125 as a one time fee.

They also charge $50 per window installed.

If the number of new windows installed is w, then it means that to install w new windows, they will charge an additional:

w * 50 = $50w

This will be in addition to the one time fee.

Let T be the total cost of installation.

Therefore, the total cost for installing w new windows (in dollars) is:

T = 125 + 50w
