Answer:
8.1 (I know someone already answered but I want the points lol)
Step-by-step explanation:
Change the yards to feet. 45 x 3(3 feet=1 yard) and you get 135
Divide that number by the number of 5 feet ribbons purchased you get 27. Then multiply the cost of 5 feet of ribbon($0.80 x 27 = 21.6)
Then subtract the original 50 yards' $13.50 from that and you get profit. (21.6-13.50=8.1)
