Answer:
Step-by-step explanation:
buying the windows and having them installed costs $ 7699.25
installation alone costs 3325
therefore, the cost of the windows is : 7699.25 - 3325 = 4374.25
and if they are paying 230.25 per window, then there is
4374.25 / 230.25 = 18.997 windows
let me check something...
18 * 230.25 = 4144.50
19 * 230.25 = 4374.75
if ur numbers are written correctly, they can only buy 18 windows.....they would be short 50 cents from buying 19 windows
