I have $150,000,000 and planning on purchasing an item that costs $200,000.
\n" ); document.write( " I can only buy one at a time and every time I purchase this item the price increases by $1,800.
\n" ); document.write( " How many times can I purchase this item?
\n" ); document.write( ":
\n" ); document.write( "To cut down on typing do this in 1000's
\n" ); document.write( ":
\n" ); document.write( "Let n = no. of items you can buy with 150 million
\n" ); document.write( "Assuming the 1st one is 200k, 1800 added each one after that
\n" ); document.write( ":
\n" ); document.write( "200n + 1.8(n-1) = 150000
\n" ); document.write( "200n + 1.8n - 1.8 = 150000
\n" ); document.write( "201.8n = 150000 + 1.8
\n" ); document.write( "n = \"150001.8%2F201.8\"
\n" ); document.write( "n ~ 743 times \n" ); document.write( "
\n" );
