\n" ); document.write( "-----------------
\n" ); document.write( "price of ball + tax on ball + price of grapefruit + tax on grapefruit = 515 cents
\n" ); document.write( "-----------
\n" ); document.write( "Let price of ball be \"x\" cents
\n" ); document.write( "0.07x = 18 cents
\n" ); document.write( "x = 257 cents (price of the ball)
\n" ); document.write( "----------------------
\n" ); document.write( "257.14 + 18 + price of grapefruit = 515
\n" ); document.write( "grapefruit = 515 - 275
\n" ); document.write( "grapefruit = 240 cents
\n" ); document.write( "===========================
\n" ); document.write( "Answer:
