The cost of a jacket increased from $80.00 to $90.40. what is the percentage increase of the cost of the jacket?

So the Percentage Increase in Price would be 13%

Step-by-step explanation:

Given:

Old Price of jacket = $80.00

New Price of Jacket = $ 90.40

To Given:

Percentage Increase = ?

Solution:

Percentage Increase %

Now we will find the difference in values

Difference = New Value - Old Value

                 = 90.40 - 80.00

                 = $ 10.40

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)
