Question 521236: Mr. Smith had to pay 75 cents a square foot for a glass to replace a broken window which was square and measured 4 feet from top to bottom. Yet Mr. Smith paid $6.00 for the single sheet of glass required to fix the window. Explain this total.
I am unsure how to convert to square feet. Only thing I could come up with was P=16 and multiply that by the .75 which gives you 12. So from there all I can say is he got it half off but as i said i dont know how to do square feet. THank you Very much!!
