Hello,
\n" ); document.write( "Let's set it up this way. Let \"p\" be the price of the calculator. Then we can write this equation.
\n" ); document.write( "p+(6% times p)=$137.80 Rewritten it looks like this:
\n" ); document.write( "p+.o6p=137.8 Combine like terms to get:
\n" ); document.write( "1.06p=137.8 Divide both sides by 1.06 to get:
\n" ); document.write( "p=130
\n" ); document.write( "Now we know the calculator cost $130 but check it out for yourself to see when you multiply 130 time 6%. You should get what the tax is, right?
