OpenStudy (caitlinnr14):

OpenStudy (anonymous):

im clueless

OpenStudy (ja1):

I forgot the formula ugh *punches face*

OpenStudy (ja1):

One sec let me get it...

OpenStudy (anonymous):

I got $113

OpenStudy (anonymous):

yes 112.72

OpenStudy (anonymous):

but i could be wrong

OpenStudy (ja1):

Isn't it basically \[O * .5 = P\] O = Original price P = End Price

OpenStudy (anonymous):

I did this x*1.05=118.65

OpenStudy (ja1):

Why 1.05?

OpenStudy (caitlinnr14):

yea me too

OpenStudy (anonymous):

but thats not a choice..thats why im stuck

OpenStudy (ja1):

Ugh I am confused and I forgot the formula for this xD so I will be of little help...

OpenStudy (caitlinnr14):

wait 112.72 isnt

OpenStudy (caitlinnr14):

a choice?

OpenStudy (anonymous):

118.65

OpenStudy (anonymous):

because of 5% sales tax. 5%=0.05 So the orginal price times sales tax should give you the difference between the orginial and the afterprice

OpenStudy (caitlinnr14):

tht ok @JA1

OpenStudy (anonymous):

nvm about what i said lol i understand what you mean now

OpenStudy (caitlinnr14):

oki

OpenStudy (ja1):

Exactly, just like in real life (america) we have a 7% tax, but we calculate it as 0.007

OpenStudy (ja1):

So do that...

OpenStudy (caitlinnr14):

man ur good @JA1

OpenStudy (ja1):

I try C: lol

OpenStudy (caitlinnr14):

haha... @JA1 so u got it @Dboy21

OpenStudy (anonymous):

@JA1 7% tax is not 0.007 it's 0.07 becaues 7/100=0.07

OpenStudy (ja1):

Yes thats what I meant xD I always mix them up, once I was shopping and had a big order so I calculated the tax and got like 100 so I was like "Wait a second" lol
