The amount of revenue brought in by racetracks may be modeled by R(t)=507t+4599 million dollars. Solve the system of equations and explain what the solution means.\r

Their intersection is for parks and racetracks revenues are equal.\r

\n" ); document.write( "\n" ); document.write( "Find that time using $\"177t%2B7335=507t%2B4599\"$ .
\n" ); document.write( " $\"%28507-177%29t=7335-4599\"$
\n" ); document.write( " $\"330t=2736\"$
\n" ); document.write( " $\"t=8.29\"$
\n" ); document.write( "This would be if counting goes to some fraction of a year.\r

\n" ); document.write( "\n" ); document.write( "Otherwise, if to nearest one year, this is 8 years after 1998. \n" ); document.write( "
