Example 6 Solve a multi-step problem BASEBALL ATTENDANCE Major League Baseball teams are divided into two leagues. During the period 1995–2001, the attendance N and A (in thousands) at National and American League baseball games, respectively, can be modeled by – = 488t2 + 5430t + 24,700and N – = 318t2 + 3040t + 25,600 A where t is the number of years since 1995. About how many people attended Major League Baseball games in 2001?
Example 6 Solve a multi-step problem With tas the number of years since 1995, about how many people attended Major League Baseball games in 2001? – = 488t2 + 5430t + 24,700and N – = 318t2 + 3040t + 25,600 A
( ) ( ) – = – 488t2 + 5430t + 24,700 + 318t2 + 3040t + 25,600 M ( ) ( ) ( ) – – = 488t2 + 5430t + 318t2 3040t + 24,700 + 25,600 – = 806t2 + 8470t + 50,300 STEP 2 Substitute 6 for t in the model, because 2001 is 6 years after 1995.
