Can I have someone check this please?

I wouldn't want to do the whole page, then find out I had done them all wrong. :(

[Percents of Change]

A $100 digital watch is now $72
Decrease, 72/100 = negative percent.
100/72.00 = .72
.72 - 1 = 30%?

Thanks.

30% is my final answer, correct?

so, isn't the change in the price $28 ?

so percent of change is 28/100 = 28%

Your last two lines make no sense.
100/72.00 = .72 ??
100/72 = 1.388889 not .72
(why are you dividing 100 by 72 in the first place?)

.72 - 1 = 30%? ????? How can that be 30% ?
.72 - 1 = -.28

Well, sorry -.-

Thanks for the answer, lol.

I thought it would be 28.

Can you type the full question to give us the depreciation rate???

To determine whether your answer of 30% is correct, let's go through the process step by step.

First, you correctly recognized that the price decreased from $100 to $72, indicating a decrease in value. To find the percent change, you need to calculate the percentage by which the value decreased.

To get the percentage change, you divide the decrease in value ($100 - $72 = $28) by the original value ($100), and then multiply by 100 to express it as a percentage:

($28 / $100) * 100 = 28%

So, according to the calculations, the percent change is 28%.

Therefore, your final answer should be 28%, not 30%.
