Question

What is the original list price if the didcount is $35 and the discount price is 10%?

Answer 1

$38.89

Explanation:

so lets use the discount price formula:

`(n-0)/(0)=(-percent)/(100)`

where

n=new price(35)

o=original price

percent=(10)(since its a discount problem, percent will be negative)

so lets substitute these values in the equation:

`(35-o)/(o)=(-10)/(100)`

2) cross multiply:

100(35-o)=-10o

3500-100o=-10o

3500=90o

38.88=o

hence discount price is $38.89(rounded up form 38.8888888889)
