To visit the of the empire state building, a ticket cost $4.00 in 1999.in 2009 ,the price rose to 20.00. what was the percent change?

Step-by-step explanation:

i think its 500%

but im not sure

because 20 divided by 4 = 5

and 5.0 = 500%

 The percent change is 400%

Explanation:

We know that percentage change is given by the

i.e we find the difference between the original value and current value and then divide it by original value and multiply the obtained value with 100.

a negative percentage change indicates increase in value.

so we get 4 - 20 = -16

= -4

100 = -400

hence there is an increase of 400% in the percentage which is the required percentage.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
