Let P be the Pacific
\n" ); document.write( "Let C be the Caribbean
\n" ); document.write( "Let M be the Mediterranean
\n" ); document.write( ".
\n" ); document.write( "Here is the information given in the problem:
\n" ); document.write( "C = P + 13
\n" ); document.write( "M = 4P - 40
\n" ); document.write( "C + P + M = 615
\n" ); document.write( ".
\n" ); document.write( "Let's rewrite the problem substituting the values given in the question.
\n" ); document.write( "C + P + M = 615
\n" ); document.write( "(P+13) + P + (4P-40) = 615
\n" ); document.write( "Add the Ps
\n" ); document.write( "6P + 13 - 40 = 615
\n" ); document.write( "Do the addition and subtraction
\n" ); document.write( "6P - 27 = 615
\n" ); document.write( "Add 27 to each side
\n" ); document.write( "6P = 642
\n" ); document.write( "Divide each side by 6
\n" ); document.write( "P = 107
\n" ); document.write( ".
\n" ); document.write( "If P is 107, then C is 107+13, or 120
\n" ); document.write( "If P is 107, then M is (4*107)-40, or 428-40, or 388
\n" ); document.write( "Add them together to make certain the problem is correct.
\n" ); document.write( "107 + 120 + 388 does indeed equal 615.
\n" ); document.write( "Success!
\n" ); document.write( ".
\n" ); document.write( "And now I'm ready to sail on the Princess Ruby! \n" ); document.write( "
