You have an item that you bought but you lost the sales receipt. There are no price stickers on the item but you remember you gave the clerk $40 and received x in change. Given that the sales tax rate in the state is 6.65%, how would you go about figuring the cost of the item itself? You may have more than one unknown but create a formula for this relationship.

\n" ); document.write( "Let p = price of the item

\n" ); document.write( ".065x = tax on the item
\n" ); document.write( ":
\n" ); document.write( "x = 40 - (p+.0665p)
\n" ); document.write( "x = 40 - 1.0665p
\n" ); document.write( ":
\n" ); document.write( "If you returned the item to a store in another state with a different tax rate, what would the tax rate need to be for you to get back more money that you paid out?
