An electrician bought 80 feet of electrical wire and used 65 feet of it. What percent of the wire went unused?

 Seventy percent of a roof, or 1400 square feet of the roof, has been re-shingled. What is the total area of the roof?

Unused percentage =15/80 *100 =1500/80 = 150/8 = 75/4 = 18.75%

Reshingled = 1400  sq feet = 70%

100% = 1400/0.7 = 2000 sq feet
