Find the selling price. Cost to store: $20 Mark-up: 15% What is the selling price?

$23

Step-by-step explanation:

First, we find what is 15% of $20.

0.15 times 20 is 3. Therefore, we know there was a markup of $3.

Then, we add the mark-up to the cost to store, and get $23.

So, the selling price is $23.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

the solution is 12x-6y
