Question

A craft store buys 50 yards of satin ribbon for 13.50. The store. The store sells the ribbon by the foot.A customer can purchase 5 feet of ribbon for $0.80. How much profit does the craft store earn if it sells 45 yards of the ribbon and scraps the rest?

Answer 1

Convert 45 yards of ribbon to feet through proper conversion factor. 

   (45 yards)(3 ft / 1 yard) = 135 feet

Divide this number by 5 to determine the number of 5-ft ribbon that customers can purchased.

     n = 135 ft / 5 ft = 27

Then, multiply by $0.80.

    R = (27)($0.80) = $21.6

The profit is equal to $21.6 and $13.50,

     P = $21.6 - $13.50 = $8.1

Answer: $8.1
