Question

how do I set up this problem ? if the store is offering a 14%discount and yao pays $670.8 what was the marked price?

Answer 1

does anyone help anyone on here ? or is it just a chat session I have went on here twice and have not gotten a response

Answer 2

does that mean "after the discount"?

Answer 3

yes

Answer 4

670.80x0.14

Answer 5

our instructor says we have to show the 5 steps

Answer 6

if so, then you know
\[\$670.80=.86P\] and so \[P=670.80\div .86\]

Answer 7

so it is A=p-rP

Answer 8

reasoning that if you get a 14% discount, you pay 86% of the price

Answer 9

right he said you subtract the 14 from 100

Answer 10

by the distributive law
\[P-rP=(1-r)P\] so no need for the first step
just subtract \(.14\) from \(1\) or 14% from 100%

Answer 11

so it will look like this it would be 670.8-.86=.86P right?
