Solve the problem.The table shows the populations of two different towns for various years. Use the data from 1990 and 1998 to write a system of equations and to predict the year in which the populations of the two towns will be equal. Let x represent the number of years since 1990 and y the population (in thousands). 
A. y = 1.2x + 17.3;
y = - 0.91x + 54.5;
About 2007
B. y = 1.2x + 15.6;
y = - 0.91x + 54;
About 2008
C. y = 1.1x + 16;
y = - 0.85x + 53.5;
About 2011
D. y = 1.1x + 20.4;
y = - 0.85x + 50.1;
