susie has $3.15 in quarters and nickles. there are 23 coins. how many of each type of coin are ther? us the five step method and a table in solution the problem.
\n" ); document.write( "------------------------------------
\n" ); document.write( "Quantity Equation: q + n = 23
\n" ); document.write( "Value Equation::::25q+5n = 315 cents
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "Multiply the Quantity Equation by 5 to get:
\n" ); document.write( "5q + 5n = 115
\n" ); document.write( "---
\n" ); document.write( "Subtract that from the Value Equation to get:
\n" ); document.write( "20q = 200
\n" ); document.write( "q = 10 (# of quarters)
\n" ); document.write( "---
\n" ); document.write( "Substitute into q + n = 23 to solve for \"n\":
\n" ); document.write( "10 + n = 23
\n" ); document.write( "n = 13 (# of nickels)
