Converting percentage to a decimal :
50%= 50 / 100 = 0.5
What is 50% of 15
=50% * 15
=0.5 * 15
=7.5
I would assume that you convert 2.5 ounces into punds which would make it 0.15 lbs.
OK my friend if you times 15 by each of the amount of hours you will find out which one it is but in this case it will be 15 times 6 hours will equal out to be $90
