Todd has 48 words to spell for a puzzle. His mother says she will pay him $1.00 for every word he spells correctly but he has to pay her $0.60 for every word he spells incorrectly. If Todd makes $19.20, how many words did he spell correctly?
\n" ); document.write( "Define the variable, create the equation, and solve.
\n" ); document.write( "---------------------------------------------------------
\n" ); document.write( "Let x be the number of words correctly spelled.
\n" ); document.write( "Let y be the number of words he misspelled.
\n" ); document.write( "---------------------------------------------------------
\n" ); document.write( "He received 100x cents
\n" ); document.write( "He paid out 60y cents
\n" ); document.write( "-----------------------------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Equation: x + y = 48
\n" ); document.write( "Value Equation::::100x - 60y = 1920 cents
\n" ); document.write( "-----------------------------
\n" ); document.write( "Multiply thru the Quantity Equation by 60 to get:
\n" ); document.write( "60x + 60y = 60*48
\n" ); document.write( "-------------------------
\n" ); document.write( "Add that to the Value equation:
\n" ); document.write( "160x = 1920+60*48
\n" ); document.write( "x = 30 (# of words he spelled correctly)
\n" ); document.write( "----
\n" ); document.write( "y = 18 (# of words he misspelled)
\n" ); document.write( "====================================
