use matrix to solve:
\n" ); document.write( "A working couple earned a total of $4352.The wife earned $64per day;the husband earned $8 less per day. Find the number of days worked if the total number of days worked by both was 72
\n" ); document.write( "
Shouldn't this be, \"Find the number of days worked by each person if the total number of days worked by both was 72?\"
\n" ); document.write( "It appears so, but why should I try to decipher your math problem?
\n" ); document.write( "Anyway, if so, your equations are: W + H = 72 and 64W + 56H = 4,352
\n" ); document.write( "You may need to determine how I came up with these 2 equations and then solve them using matrices.
\n" ); document.write( "**Hint: One worked 40 days while the other worked ????? days. You figure out the rest. \n" ); document.write( "
\n" );
