Quinn needs to buy fabric for a border to sew onto all four edges of a tablecloth. he also needs an extra 0.875 feet of fabric to make a matching potholder. the length of the table cloth is 4/3 of its width (w) in feet. the total amount of fabric needed (f), in feet, is represented by the equation below.
f=2 (w+4/3 w) + 0.875
