the sale price of a computer at 15% off is \$746.30. What is the regular price?

• math - ,

OK, Jazz. It's your turn now. :-) How do you think you'd solve that problem?

• math - ,

umm.... like claudia did??? :P

• math - ,

I'm don't think so. I think she had an error so I deleted her post.

• math - ,

no im just kidding i know.. 0.15 x 746.30?

• math - ,

wait.. then u subtract that from the original nubmer??

• math - ,

r u still there?? :( did u leavee??

• math - ,

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.

• math - ,

oh ur still here yay!!!!!:D im so happy now!

• math - ,

Does 0.15 * 746.30 give you a reasonable number?

The computer must originally cost more than 746.30.

• math - ,

ooo i get it now. so 749.30 x 0.15
then add that to the original number???

• math - ,

Nope.

100 - 0.15 = 0.85

0.85x = 746.30
x = ?

• math - ,

aww man i was sure i had it.hehe guess not! good thing u were here.thks so much for all of this!!

• math - ,

oh and so x equals 8.78?

• math - ,

Come on, Jazz. You're looking for the original price of the computer. It must be over \$800. Right?

• math - ,

ahh!! im so confused.

• math - ,

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
= 858.24

so what im i doing wrong.
homework over this and i dont
want to get it wrong

• math - ,

i have no idea. im so sorry.

• math - ,

oh im not talking to u claudia, don't worry. ill try and help but im not so good at this. im sure ms sue could help u though!

• math - ,

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?

• math - ,

ooooooo!!!!! yes that makes perfect sense!! im sorry my brains not working right now.

• math - ,

Good night Jazz. Get a good night's sleep and it will look better in the morning. <g>

• math - ,
