Yesterday the price of the book was $9.84 , today the price is $9.71. What is the percentage decrease?

@Easyaspi314

I gave you the formula before.....
Percent decrease = change in price/original price
OpenStudy (solomonzelman):
I mean 9.84 / (x/100) = 9.71
OpenStudy (anonymous):
@SolomonZelman so it would be 9.7 if you round it
OpenStudy (anonymous):
Change in price = $9.84 - $9.71 = .07

so is it 9.8 ?
OpenStudy (anonymous):
Sorry...difference is $9.84 - $9.71 = .13
OpenStudy (anonymous):
so the answer is .13 and that is already rounded?
OpenStudy (anonymous):
So it is .13/9.84 = .013211
OpenStudy (anonymous):
You can change that to a percent.

idk how
OpenStudy (solomonzelman):
My bad,
do what Easyaspi314 said, subtract $9.84 - $9.71, and then put over 9.84
he beat me

Can you change a decimal to a percent?
OpenStudy (solomonzelman):
B/c .13 is the same as 13%
OpenStudy (anonymous):
so its 13% is the answer?

.a = times 100= a%
OpenStudy (anonymous):
Take the decimal point and moce it 2 places to the right....you get
1.3211%
OpenStudy (solomonzelman):
to the nearest dollar, yes
OpenStudy (anonymous):
1.3 %
OpenStudy (anonymous):
or 1.3% to the nearest tenth

Oh, my bad, sorry for misleading....
OpenStudy (anonymous):
.13 is just 13 cents...that is just the difference in price
