Answer: $49.78
Step-by-step explanation: $15.75 + $28.79 + $5.24 = $49.78
We know that
if <span>4 electricians can complete a job in 8 hours
then
</span>100% of a job -------> 8 hours
x------------------> 1 hour
x=100/8----> x=12.5%
divide by 4 electricians
12.5%/4-----> 3.125%
that means each electrician can complete 3.125% of a job in 1 hour
therefore
3 electricians-----> 3*3.125%----> 9.375% in 1 hour
so
9.375%-----------> 1 hour
100%--------------> x
x=100/9.375----> x=10.67 hours
the answer is
10.67 hours

Answer:
5/8
Step-by-step explanation:
.625 can equal 625/1000
and you can shrink the answer down with simplification.
cause you can divide both numerator and denominator by 5
625/1000 = 125/ 200
And we can divide both sides again by 5.
125/ 200 = 25/ 40
and we can divide both sides again by 5 once again.
25/ 40 = 5/ 8
