First we start with the value of coins equation: \n" ); document.write( "(i) 5N + 10D = 100 \n" ); document.write( "Second, we have the number of coins equation: \n" ); document.write( "(ii) D = 2N \n" ); document.write( "By substitution, we get \n" ); document.write( "(iii) 5N + 10(2N) = 100 \n" ); document.write( "solving for N, we get \n" ); document.write( "25N = 100 \n" ); document.write( "N = 4 \n" ); document.write( "This means that D =8. \n" ); document.write( " |
