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

vitfil [10]

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:

$\sf{\frac{115}{100}\times 20=x}$

Simplify that:

$\sf{\frac{115}{5} = x}$

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

$\huge{\boxed{\bf{x=23}}}$

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

11-3(x+2) Expand and simplify

statuscvo [17]

Answer:

5-3x

Step-by-step explanation:

To expand this, we start with the distribution of -3 into the parentheses containing x+2

This leaves us with

11-3x-6

From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6

We combine them by subtracting 11-6 to get 5.

This leaves us with our answer,

11-6-3x

5-3x

An alternate way of writing this would be

-3x+5

But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now
