Three Pairs of jeans and six shirts caost $104.25. The cost of 4 jeans and 5 shirts is $112.15. Find the cost of each pair of jeans and each shirt.
\n" ); document.write( "-------------------
\n" ); document.write( "Start by writing down what it says.
\n" ); document.write( "3J + 6S = 10425 eqn 1 from sentence 1
\n" ); document.write( "4J + 5S = 11215 eqn 2 from sentence 2
\n" ); document.write( "Now you have 2 eqns in 2 unknowns. There are several ways to solve them.
\n" ); document.write( "I'll use elimination
\n" ); document.write( "Multiply the 2 eqns to get the same number of one of the variables.
\n" ); document.write( "12J + 24S = 41700 eqn 1 x 4
\n" ); document.write( "12J + 15S = 33645 eqn 2 x 3
\n" ); document.write( "Subtract
\n" ); document.write( " 0J + 9S = 8055
\n" ); document.write( "S = 895
\n" ); document.write( "------------Sub for S in eqn 1
\n" ); document.write( "3J + 6*895 = 10425
\n" ); document.write( "3J + 5370 = 10425
\n" ); document.write( "3J = 5055
\n" ); document.write( "J = 1685
\n" ); document.write( "So the shirts cost $8.95 and the jeans are $16.85 \n" ); document.write( "
\n" );
