An electrician bought 120 feet of electrical wire and used 105 feet of it what percent of wire went unused
a. 15%
b. 12.5%
c. 8.75%
d. 7%

Step-by-step explanation:

105/120= 0.875

In order to obtain a percentage, you move the decimal point to the right two spaces.

Therefore, 0.0875 will be 87.5%

What this tells you is that 87.5% of the wire was used.

So, 100%-87.5%= 12.5% of wire was left over/unused.

answer is 17
