Revenue for the week is 2,000. labor consits of two worker's. earning 8.00 per hour. who work 40 hours each. what is labor cost as a percentage of revenue.

So, two workers working 40 hours each, that's 80 hours of work. 8 dollars per hour in pay: 8*80=640; so 640 dollars were paid to the workers. 

the labor cost is =[tex] \frac{64}{2} /tex]=32

so the labor cost is 32% of the revenue.

What is the last question i don’t see it?
