What is a tip in sales?
A tip in sales is an added monetary contribution to the worker responsible for your bill. Tips are usually in percentage form and represent a portion of the total before you add a tip.
To find a tip in sales, convert the percentage to a decimal and then add 1 to that decimal. Finally, multiply the total by this sum.
Solve
To solve, first convert the percentage into a decimal by dividing by 100.
[tex]\displaystyle \frac{10}{100}[/tex]
[tex]0.1[/tex]
Then, add 1 to this quotient.
[tex]1+0.1 =1.1[/tex]
Finally, multiply the total ($20) by this sum.
[tex]20\times 1.1[/tex]
[tex]22[/tex]
Therefore, the total cost is $22.00.
