find percent of change round to the nearest whole percent if necessary State weather the percent of the change is an increase or decrease. original:$85. new:$60

Respuesta :

We have this formula to find the percent change:

To calculate percentage decrease: First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage increase.

Difference between the two = original price - new price = 85-60 = 25

Now let us divide the decrease by original price = 25/85 = 0.294

Next step is multiply it with 100 , so we have 0.294*100= 29.4

since our answer is positive so its a percentage decrease.

So percentage decrease is 29.4% or 29%
