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 ![= \frac{480}{30} = 16.](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B480%7D%7B30%7D%20%3D%2016.)
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 ![= \frac{15}{100} (16) = 0.15 (16)= 2.4.](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B15%7D%7B100%7D%20%2816%29%20%3D%200.15%20%2816%29%3D%202.4.)
So her 15% increase amounts to $2.4.
So the hourly rate for this month ![16 + 2.4 = 18.4.](https://tex.z-dn.net/?f=16%20%2B%202.4%20%3D%2018.4.)
So Karmin will make $18.4 for working 1 hour.
