Peggy had four times as many quarters as nickels. She had $2.10 in all. How many nickels and how many quarters did she have?
\n" ); document.write( "Which of the following equations could be used to solve the problem?
\n" ); document.write( "---------------------
\n" ); document.write( "Quantity Equation: q = 4n
\n" ); document.write( "Value Equation: 5n + 25q = 210 cents
\n" ); document.write( "------------------------------------------
\n" ); document.write( "Substitute for \"q\" and solve for \"n\":
\n" ); document.write( "5n + 25(4n) = 210
\n" ); document.write( "5n + 100n = 210
\n" ); document.write( "105n = 210
\n" ); document.write( "---
\n" ); document.write( "n = 2 (# of nickels)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"q\":
\n" ); document.write( "q = 4n
\n" ); document.write( "q = 4*2 = 8 (# of quarters)
