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 [tex]= \frac{480}{30} = 16.[/tex]
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 [tex]= \frac{15}{100} (16) = 0.15 (16)= 2.4.[/tex]
So her 15% increase amounts to $2.4.
So the hourly rate for this month [tex]16 + 2.4 = 18.4.[/tex]
So Karmin will make $18.4 for working 1 hour.
