Finding the percent of change. How do I solve this?

Question

A radio is $25.00 one month. The next month its price increased by $6.00. The original price of a CD player is $68.00 then its reduced by $12.00. How do I find the percent of change?

Answer 1

Simple.
You divide the 6.00 by the 25.00 = .24 = 24%
12.00 / 68 = 0.1764705882352941176470588235 so = 17.65%

Just remember the starting amounts are 100%, so that is what you divide by.

Answer 2

The percent change is
[(Amount of change) divided by (original price)] x 100

a positive answer indicated a % increase, negative indicates a % decrease

In the case of the radio, that's
6/25, which equals 0.24 or 24%

in the case of the CD player, it's
(-12)/68, which equals -0.1765 or 17.65% decrease

Answer 3

Radio price increase = (6/25) X 100 = 24 per cent
CD price decrease = (12/68) X 100 = 17.647 per cent

Answer 4

Ok. For the first one, take $6 and divide it by $25. That gives you .24 Multiply that number by 100, and you have your percent. The price increased 24%.

Second one. $12 divided by $68, then multiply it by 100. The cd player decreased its price by 17.6%

Answer 5

New price divided by the old price. Now remember the change includes the last price. So if something increased it would be more than 100 percent

Answer 6

You can calculate percentage change using the following formula:

Let:

A = original figure

B = new figure

Thus % change = (B - A) x 100 / A

If B is greater than A, there is a % increase

If A is greater than B, there is a % decrease (in this case B - A will give a minus figure)

Answer 7

% of change = increase (or decrease) divided by the original price.

So 6.00 / 25.00 = 24% increase
12.00 / 68.00 = ________ decrease (You figure that one)

Answer 8

$6/$25 = 24%

$12/$68 = -18%

Answer 9

% of change = amount of change divided by original price, expressed as a percent
