document.write( "Question 914789: A vendor has learned that, by pricing caramel apples at $1.50, sales will reach 133 caramel apples per day. Raising the price to $2.25 will cause the sales to fall to 103 caramel apples per day. Let y be the number of caramel apples the vendor sells at x dollars each. Write a linear equation that relates the number of caramel apples sold per day to the price x.

$\"+y+=+133+-+%28%28+x+-+1.5+%29+%2F+.75+%29%2A30+\"$ answer
\n" ); document.write( "Check the equation:
\n" ); document.write( "suppose
\n" ); document.write( " $\"+y+=+103+\"$
\n" ); document.write( " $\"+103+=+133+-+%28%28+x+-+1.5+%29+%2F+.75+%29%2A30+\"$
\n" ); document.write( " $\"+30+=+%28+x+-+1.5+%29+%2F+.75+%29%2A30+\"$
\n" ); document.write( " $\"+1+=+%28+x+-+1.5+%29%2F+.75+\"$
\n" ); document.write( " $\"+x+-+1.5+=+.75+\"$
\n" ); document.write( " $\"+x+=+2.25+\"$
\n" ); document.write( "OK
\n" ); document.write( "----------
\n" ); document.write( "Soppose
\n" ); document.write( " $\"+x+=+3+\"$ ( $3 )
\n" ); document.write( " $\"+y+=+133+-+%28%28+3+-+1.5+%29+%2F+.75+%29%2A30+\"$
\n" ); document.write( " $\"+y+=+133+-+%28+1.5+%2F+.75+%29%2A30+\"$
\n" ); document.write( " $\"+y+=+133+-+2%2A30+\"$
\n" ); document.write( " $\"+y+=+133+-+60+\"$
\n" ); document.write( " $\"+y+=+73+\"$
\n" ); document.write( "Correct because every $.75 increase in price
\n" ); document.write( "will lower $\"+y+\"$ by $\"+30+\"$ , and
\n" ); document.write( "$3 is $1.50 + ( $.75 )*2
\n" ); document.write( "and that makes a decrease of 60 in $\"y\"$
\n" ); document.write( "Make sense?\r
