When x number of units are sold, the price of each unit (in dollars) is given by p = -x/2 + 75. Find the unit price when the following quantities are sold: 2,7,9,11.
\n" ); document.write( "Let x=2 and solve for p:
\n" ); document.write( " $\"p=-%282%29%2F2%2B75\"$
\n" ); document.write( " $\"p=-1%2B75\"$
\n" ); document.write( " $\"p=74\"$
\n" ); document.write( "When 2 units are sold, the unit price is $74.
\n" ); document.write( "Let x=7
\n" ); document.write( " $\"p=-%287%29%2F2%2B75\"$
\n" ); document.write( " $\"p=-3.5%2B75\"$
\n" ); document.write( " $\"p=71.5\"$
\n" ); document.write( "When 7 units are sold, the unit price is $71.50
\n" ); document.write( "Let x=9
\n" ); document.write( " $\"p=-%289%29%2F2%2B75\"$
\n" ); document.write( " $\"p=-4.5%2B75\"$
\n" ); document.write( " $\"p=70.5\"$
\n" ); document.write( "When 9 units are sold, the price is $70.50
\n" ); document.write( "Let x=11
\n" ); document.write( " $\"p=-11%2F2%2B75\"$
\n" ); document.write( " $\"p=-5.5%2B75\"$
\n" ); document.write( " $\"p=69.5\"$
\n" ); document.write( "When 11 units are sold, the price is $69.50
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
