An appliance store decreases the price of a 19-in. tv ser 15% to a sale price of $534.65. What was the original price?

Question

dont know why I have to have a description? Im not good at word problems..

Answer 1

the question asks for the original price, right?

 

so represent it with a variable

 

let P = original price

 

the price dropped 15%.

 

what is 15% of the original price that we called P

 

well, 15% is .15 as a decimal so 15% of P is .15 x P

 

if the price was reduced, that means we subtract off the 15%

 

so now we have   P - .15P

 

the question tells us that this sale price that we wrote is equal to $534.65

 

So now we write the equation

 

P - .15P = 534.65

 

.85P = 534.65

 

P = $629 is the original price

 

I hope this helps you figure out other questions that are similar to this one.

Answer 2

The discount is 15% therefore you pay 85% of the original price.

 

Set up the equation to reflect that 85% of the original price is $534.65. Solve for x.

 

0.85x=$534.65

Answer 3

Original Price - 15% off = $534.65

 

(Original Price) - (0.15)*(Original Price) = $534.65

 

(Original Price)*(1 - 0.15) = $534.65

 

(Original Price)*(0.85) = $534.65
