Rafiq pays $1.10 for 3 pencils. He pays with 11 coins including 1 quarter. The rest of the coins are dimes and nickles. Which combination of coins below did Rafiq use including a quarter?
\n" ); document.write( "A. 9 nickles, 4 dimes
\n" ); document.write( "B. 7 nickles, 5 dimes
\n" ); document.write( "C. 5 nickles, 6 dimes
\n" ); document.write( "D. 3 nickles, 7 dimes
\n" ); document.write( "------------------
\n" ); document.write( "You have one quarter: value is 25 cents
\n" ); document.write( "Let number of nickels be \"x\" ; value is 5x cents
\n" ); document.write( "Number of dimes is 11-1-x = 10-x ; value is 10(10-x)=100-10x cents
\n" ); document.write( "-------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value + value = 110 cents
\n" ); document.write( "25 + 5x + 100-10x = 110
\n" ); document.write( "-5x = -15
\n" ); document.write( "x = 3 (# of nickels)
\n" ); document.write( "10-x = 7 (# of dimes)
\n" ); document.write( "========================
