Jamal works as an electrician’s apprentice. He rewired 4 electrical outlets in 1 1/2 hours. If he works at the same pace for 7.5

Anna35 [415]

Answer: 20 outlets.

Step-by-step explanation:

We know that Jamal rewired 4 electrical outlets in 1 1/2 hours. This time can be rewritten as a decimal:

$(1+\frac{1}{2})hours=1.5hours$

Then, if he works at the same pace for 7.5 hours you can calculate the number of outlets that he will rewire with:

$\frac{1.5}{4}=\frac{7.5}{x}$

Being "x" the number of outlets that Jamal will rewire.

Finally, you have to solve for "x":

$\frac{1.5}{4}=\frac{7.5}{x}\\\\x(\frac{1.5}{4})=7.5\\\\x=(7.5)(\frac{4}{1.5})\\\\x=20$

He will rewire 20 outlets.
