Karmin will make $18.4 for working an hour after the increase.
Step-by-step explanation:
Step 1:
First, we need to determine how much Karmin made an hour.
Karmin's hourly rate 
So Karmen made $16 every hour that she worked. She worked for 30 hours and earned $480.
She will get a 15% increase in her hourly rate this month.
Step 2:
We need to determine how much 15% of $16 is.
15% of $16 
So her 15% increase amounts to $2.4.
So the hourly rate for this month 
So Karmin will make $18.4 for working 1 hour.
The basic unit of length in the metric system is the meter. Grams are
used to measure weight and liter is used to measure liquid capacity
besides, it is used so that you can express very large and very small numbers in a short
unambiguous manner.
Example Instead of saying "three thousand
million" meters
They classify the decimal place of the basic unit. ie, the meter is
classified with milli (1/1000), centi(1/100), deci (1/10), Deca (10),
Hecto (100), Kilo (1000).
