Answer:
$0.21
Step-by-step explanation:
Let x be the amount of money earned per hour before raise and y be amount of money earned per hour after raise.
We have been given that before raise he worked 38 hours and earned $220. We can represent this information as:
We are also told that the next week, he received a raise. After raise he worked 30 hours and made $180. We can represent this information as:
.
Let us solve for x and y.
Therefore, before raise Mike earned $5.7894 per hour.
![y=\frac{180}{30}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B180%7D%7B30%7D)
![y=6](https://tex.z-dn.net/?f=y%3D6)
Therefore, after raise Mike earned $6 per hour.
Now let us subtract 5.7894 from 6 to find Mike's raise.
![\text{Amount of raise}=6-5.7894](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20raise%7D%3D6-5.7894)
![\text{Amount of raise}=0.2106\approx 0.21](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20of%20raise%7D%3D0.2106%5Capprox%200.21)
Therefore, amount of Mike's raise to the nearest cent is $0.21.
