document.write( "Question 466504: Chris has two large dogs that want to go out all the time. He has a big fenced in yard so he decided to buy a \"doggie door\". He did research online and found a pet supply company that was cheapest. He ordered the door online and was given a 20% discount plus a shipping and handling charge of $4.95. If Chris paid a grand total for the door of $43.99, what was the original price of the door?\r

let x = original price of the door.
\n" ); document.write( "the sale price of the door is equal to x -.2x = .8x
\n" ); document.write( "the total cost is equal to 43.99 which is the sum of the sale price of the door plus the shipping and handling.
\n" ); document.write( "this leads to:
\n" ); document.write( "43.99 = .8x + 4.95
\n" ); document.write( "subtract 4.95 from both sides of this equation to get:
\n" ); document.write( "43.99 - 4.95 = .8x
\n" ); document.write( "simplify this to get:
\n" ); document.write( "39.04 = .8x
\n" ); document.write( "divide both sides of this equation by .8 to get:
\n" ); document.write( "39.04 / .8 = x which leads to:
\n" ); document.write( "x = 39.04 / .8 = 48.8
\n" ); document.write( "the original price of the door is $48.80
\n" ); document.write( "20% off the original price leads to a sale price of 39.04
\n" ); document.write( "add shipping and handling of 4.95 to get a total price of 39.04 + 4.95 = $43.99
\n" ); document.write( " \n" ); document.write( "
\n" );
