pencils are .25 each & notebooks are 1.00 each. if we have $20.00 how many pencils & pens did we puchase? how much did we spend on each.
\n" ); document.write( "Please show work.
\n" ); document.write( "There are a total of 52 pencils & notebooks.
\n" ); document.write( "-----
\n" ); document.write( "You have already said the pencils are 25 cents and the notebooks are $1.
\n" ); document.write( "---
\n" ); document.write( "You have information for a value equation and a Quantity Equation:
\n" ); document.write( "Value Equation::0.25p + 100*n = 2000 cents
\n" ); document.write( "Quantity Equation: p + n = 52 pieces
\n" ); document.write( "---
\n" ); document.write( "Multiply thru 1st by 100
\n" ); document.write( "Multiply thru 2nd by 25
\n" ); document.write( "-----
\n" ); document.write( "25p + 10000n = 200000 cents
\n" ); document.write( "25p + 25n = 25*52
\n" ); document.write( "----
\n" ); document.write( "Subtract and solve for \"n\":
\n" ); document.write( "9975n = 198700
\n" ); document.write( "---
\n" ); document.write( "n = 19.919799
\n" ); document.write( "---------------
\n" ); document.write( "Note: That does not make any sense.
\n" ); document.write( "The number of notebooks sold must be a whole number.
\n" ); document.write( "Please check the wording of your problem.
