let the cost of one sandwiches be x and the cost of one cup of coffee be y
\n" ); document.write( "since you buy 5 sandwiches and 3 cups of coffee and the total cost is 12.35. the equation will be
\n" ); document.write( "5x + 3y = 12.35
\n" ); document.write( "But you already know the sandwiches are 1.75 each, so you plug it in the equation:\r
\n" ); document.write( "\n" ); document.write( "5(1.75) + 3y = 12.35
\n" ); document.write( "8.75 + 3y = 12.35
\n" ); document.write( "3y = 12.35 - 8.75
\n" ); document.write( "3y = 3.6
\n" ); document.write( "y = 1.2
\n" ); document.write( "TA-DAH
\n" ); document.write( "Your answer is 1.2 for each of the cup of coffee :D \n" ); document.write( "
