To convert a percent to a decimal, we divide by 100. This is the same thing we do to convert a percent to a fraction.
Answer:
$0.13 (this is a rounded answer)
Step-by-step explanation:
The unit cost is the cost of a 1 ounce bottle so you would divide the cost by the total number of ounces:
$2.00 divided by 16 is 0.125 but you would round because you need a cost not a decimal.
So your final answer would be $0.13 per ounce.
5√11 - 12√11 - 2√11 = (5 - 12 - 2)√11 = -9√11
