what is the total cost for a $20 haircut with a 15% tip

So you are going to pay $20 and then a 15% tip on top of the 20.

And the 15% tip is 15% of $20.

To do less work, you can basically do 115% of 20 to find out the total cost instead of doing 15% of 20 and then adding that to 20.

Saying that x is the final price to pay, and converting the percents to fractions we get:

[tex]\sf{\frac{115}{100}\times 20=x}[/tex]

Simplify that:

[tex]\sf{\frac{115}{5} = x}[/tex]

And simplifying that further, you get the final answer as:

[tex]\huge{\boxed{\bf{x=23}}}[/tex]

So you have to pay $23 after the tip :)
