1. A shopkeeper buys a certain number of bottles of mayonnaise for R100, she sells all except for ten of them which broke while being unpacked, making a profit of R50.00 If she sold each bottle R10.oo more than she originally paid for it
\n" ); document.write( "1.1. How much did he pay for one bottle?
\n" ); document.write( "1.2. how much did he sell each
\n" ); document.write( "

Let C be the cost of each bottle purchased\r\n" );
document.write( "Then # of bottles purchased = \r\n" );
document.write( "Also, # of bottles sold would be: , and sale price of each bottle = C + 10\r\n" );
document.write( "We then get: \r\n" );
document.write( "                            ------ Multiplying by LCD, C\r\n" );
document.write( "                                 \r\n" );
document.write( "                                      0 = (C - 5)(C + 20)\r\n" );
document.write( "                                      0 = C - 5       or      0 = C + 20\r\n" );
document.write( " Cost of each bottle purchased or     or      C = - 20 (ignore)\r\n" );
document.write( "\r\n" );
document.write( " Sale price of each bottle:  C + 10 = 5 + 10 = R15.

\n" ); document.write( "
