Answer:
Money which Michael make in commission = 158.7
Step-by-step explanation:
Given that,
number of hours Michael worked in a week = 40 hours
total sale of the week = 2870
commission which Micheal will get on sale = 6% above 225sale
To find,
total money Michael make in commission in the week
Commission = (2870 - 225)*6%
Commission = (2870 - 225)*6/100
Commission = 2645 *6/100
Commission = 158.7
Total money Micheal make in a week = (40*12.50) + (158.7)
= 658.7
Answer:
-15/4
C:15/-4
Step-by-step explanation:
a negative number divided by another negative number gives a positive number : -15 / - 4 = +3.75
-15/4 and 15/-4 = -3.75
15/4 = 3.75 (two positive numbers divided with each other yields a positive number)
-4/15 and 4 / -15 = 0.27
