Question

A manufacturing plant earned \$80 per a man-hour of labor when it opened. Each year, the plant earns an additional 6%per man-hour. Which expression gives the amount the plant earned per a man-hour of labor 3 years after it opened?

Answer 1

94.4$

Explanation:

3x6%= 18%

using cross multiplication you can find 18% of 80

18/100=x/80 =14.4$

then you add the 18% of 14.4$ to the original 80$ which comes out to 94.4$

Hope this helped you out a little!
