Answer:
We conclude that Jamal will rewired 20 electrical outlets for 7.5 hours.
Step-by-step explanation:
We know that Jamal rewired 4 electrical outlets in 1 and one-half hours. We calculate how many electrical outlets will he rewired for 7.5 hours.
We have the following proportion:
[tex]4:1.5=x:7.5\\\\1.5x=4\cdot 7.5\\\\1.5x=30\\\\x=\frac{30}{1.5}\\\\x=20[/tex]
We conclude that Jamal will rewired 20 electrical outlets for 7.5 hours.
