Answer: $22
Step-by-step explanation:
First we calculate for the sale price.
We have to find how much is 60% of 50.
We do this by:
![50 *0.6=\\](https://tex.z-dn.net/?f=50%20%2A0.6%3D%5C%5C)
This equals 30.
We now subtract the 30 from the 50 to get our sale price.
![50 -30 =](https://tex.z-dn.net/?f=50%20-30%20%3D)
The sale price is $20.
Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.
![1+0.1](https://tex.z-dn.net/?f=1%2B0.1)
This equals 1.1
This is what we will multiply the $20 by.
![20*1.1=\\](https://tex.z-dn.net/?f=20%2A1.1%3D%5C%5C)
The total cost is $22.
