the sale price of a computer at 15% off is $746.30. What is the regular price?
0.85x = 746.30
x = ?
x = 746.3 / 0.85
x = 878
The original price of the computer was $878.
Doesn't that make sense now?
Nope.
100 - 0.15 = 0.85
0.85x = 746.30
x = ?
OK, Jazz. It's your turn now. :-) How do you think you'd solve that problem?
umm.... like claudia did??? :P
I'm don't think so. I think she had an error so I deleted her post.
Besides, I want you to think about this problem. <g>
no im just kidding i know.. 0.15 x 746.30?
wait.. then u subtract that from the original nubmer??
r u still there?? :( did u leavee??
I'm still here. I'm not a math teacher so I had to take some time to figure this one out. I'll post again in a couple of minutes.
Does 0.15 * 746.30 give you a reasonable number?
The computer must originally cost more than 746.30.
ooo i get it now. so 749.30 x 0.15
then add that to the original number???
aww man i was sure i had it.hehe guess not! good thing u were here.thks so much for all of this!!
oh and so x equals 8.78?
Come on, Jazz. You're looking for the original price of the computer. It must be over $800. Right?
ahh!! im so confused.
sorry. not trying to be rude
but now im confused. :/
we are working in our class in
something related to this.
so wouldnt an increase in 15% be a multiplier of 1.15
so you do 746.30*1.15= 858.24
or another way i solve it is
by doing 746.30*.15=111.94
so then u add 746.30+111.94
= 858.24
so what im i doing wrong.
why was my answer wrong.
can you please help. im doing
homework over this and i dont
want to get it wrong
