You are selling banana bread that costs P 5 each. Each week, you have 50
\n" ); document.write( "customers. When you decrease the price by P1, you expect 30 customers to be
\n" ); document.write( "added. What is the price of the banana bread that yields a maximum profit?\r
\n" ); document.write( "\n" ); document.write( "c. If the revenue (R) = number of bread × bread price. Write the equation of
\n" ); document.write( "the quadratic function given the situation above?
\n" ); document.write( "
\r\n" );
document.write( "Let x = the number of p30 reductions in price \r\n" );
document.write( "\r\n" );
document.write( "Then\r\n" );
document.write( "\r\n" );
document.write( "the price will be reduced from p(5) to p(5-1*x), or p(5-x)\r\n" );
document.write( "\r\n" );
document.write( "and\r\n" );
document.write( "\r\n" );
document.write( "the number of customers will grow from 50 to 50+30x\r\n" );
document.write( "\r\n" );
document.write( "Profit = (50+30x)(5-x)\r\n" );
document.write( "Profit = 250-50x+150x-30x2\r\n" );
document.write( "Profit = 250+100x-30x2\r\n" );
document.write( "Profit = -30x2+100x+250\r\n" );
document.write( "\r\n" );
document.write( "Maximum profit, use vertex formula \"x=-b%2F%282a%29=-100%2F%28%282%29%28-30%29%29=100%2F60+=+%221.666...%22\"\r\n" );
document.write( "\r\n" );
document.write( "So we reduce the price by 1.666... reductions of 1p each.\r\n" );
document.write( "\r\n" );
document.write( "So the new reduced price is p5 to p5-p1.666... = p3.333...\r\n" );
