Question 981381: Need steps on how to solve this word problem. Thank you
Based on data from 1998 and 1999, the amount of revenue brought in by parks can be modeled by A(t)=177t+7335 million dollars where t is the number of years since the end of 1998. 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.

Their intersection is for parks and racetracks revenues are equal.

Find that time using 177t%2B7335=507t%2B4599.
%28507-177%29t=7335-4599
330t=2736
t=8.29
This would be if counting goes to some fraction of a year.

Otherwise, if to nearest one year, this is 8 years after 1998.
