document.write( "Question 1010801: A company has a manufacturing plant that is producing quality jackets. They find that in order to produce 180 jackets in a month, it will cost $5340. Also, to produce 400 jackets in a month, it will cost $8200. Find an equation in the form y=mx+b, where x is the number of jackets produced in a month and y is the monthly cost to do so \n" ); document.write( "

You can put this solution on YOUR website!
Plot cost, $\"+C+\"$ , on the vertical axis and
\n" ); document.write( "number of jackets, $\"+n+\"$ on the horizontal
\n" ); document.write( "axis. You are given 2 points, ( n, C ):
\n" ); document.write( "( 180, 5340 )
\n" ); document.write( "( 400, 8200 )
\n" ); document.write( "--------------------
\n" ); document.write( "Use the general point-slope formula:
\n" ); document.write( " $\"+%28+C+-+5340+%29+%2F+%28+n+-+180+%29+=+%28+8200+-+5340+%29+%2F+%28+400+-+180+%29+\"$
\n" ); document.write( " $\"+%28+C+-+5340+%29+%2F+%28+n+-+180+%29+=+2860+%2F+220+\"$
\n" ); document.write( " $\"+%28+C+-+5340+%29+%2F+%28+n+-+180+%29+=+13+\"$
\n" ); document.write( " $\"+C+-+5340+=+13%2A%28+n+-+180+%29+\"$
\n" ); document.write( " $\"+C+-+5340+=+13n+-+2340+\"$
\n" ); document.write( " $\"+C+=+13n+%2B+3000+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "check answer:
\n" ); document.write( "( 180, 5340 )
\n" ); document.write( " $\"+C+=+13n+%2B+3000+\"$
\n" ); document.write( " $\"+5340+=+13%2A180+%2B+3000+\"$
\n" ); document.write( " $\"+5340+=+2340+%2B+3000+\"$
\n" ); document.write( " $\"+5340+=+5340+\"$
\n" ); document.write( "OK
\n" ); document.write( "----------
\n" ); document.write( "You can check ( 400, 8200 )
\n" ); document.write( "Also they want to use x and y, so
\n" ); document.write( " $\"+n+=+x+\"$ and $\"+C+=+y+\"$ \n" ); document.write( "

\n" );
