Lets just simply solve:-

Days:-   1         2          3        4          5         6         7                                     
           1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = Cost to rent a movie for 7 days. 

 1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 =  4.39

So, to rent a movie for 7 days it would cost $4.39.

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
Quinn needs 113/8 feet of fabric for the border of the tablecloth and the potholder. What is the width of Quinn's tablecloth?

Answers

The width of Quinn's tablecloth is 2.839 inch

Quinn needs to buy fabric for a border to sew onto all four edges of a tablecloth.

\rm Total \; amount \; of \; fabric\; needed \; f = 2(w+ (4)/(3)* w )+ 0.875.......(1) \n

\rm Length \; of\; tablecloth = L = (4)/(3) * w

According to the given condition the fabric required for potholder = 0.875 feet

Quinn needs 113/8 feet of fabric for the border of the tablecloth and the potholder.

The Total amount of fabric needed for the border and the potholder = 113/8.....(2)

So from equation (1) and (2)  we get

\rm f = (113)/(8) \n

\rm Total \; amount \; of \; fabric\; needed \; f = 2(w+ (4)/(3)* w )+ 0.875=(113)/(8) \n

Solving for w we can get

w = 2.839 inch

 

The width of Quinn's tablecloth is 2.839 inch
