You can put this solution on YOUR website!
the present value of your loan is 500,000.
\n" ); document.write( "it needs to be paid in 5 years.
\n" ); document.write( "you down payment is 200,000.
\n" ); document.write( "you need to pay 15,000 each month for the next 5 * 12 = 60 months.
\n" ); document.write( "let y equal the amount that you have paid off on the loan.
\n" ); document.write( "let x = the number of months you have to pay off the loan.
\n" ); document.write( "your equation should be y = 15,000 * x + 200,000
\n" ); document.write( "when x is 0, y is equal to 200,000 which means that your down payment was 200,000.
\n" ); document.write( "when x is 1, y would be equal to 215,000 which means you have paid off 200,000 down payment plus 15,000 first payment.l
\n" ); document.write( "when x is 2, y would be equal to 230,000 which means you have paid off 200,000 down payment plus 2 months of payments.
\n" ); document.write( "I will make everything in thousands so the legend on your graph won't be so cluttered.
\n" ); document.write( "your equation is y = 15*x + 200.
\n" ); document.write( "your graph looks like this:
\n" ); document.write( "\"graph%28600%2C600%2C-10%2C60%2C-100%2C1500%2C15%2Ax+%2B+200%2C200%2C500%2C1100%29\"
\n" ); document.write( "the horizontal lines on the graph are at y = 200, y = 500, y = 1100.
\n" ); document.write( "this corresponds to x = 0, x = 20, x = 60
\n" ); document.write( "when x = 20, you will have paid a down payment of 200 plus 20*15 = 500 thousand total payments on the loan.
\n" ); document.write( "when x = 60, you will have paid a down payment of 200 plus 60*15 = 1,100 thousand total payments on the loan.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
