Explanation Formula used: The Wronskian of any two solutions y 1 and y 2 to the equation y ″ ( t ) + p y ′ ( t ) + q y ( t ) = 0 on ( a , b ) is given by Abel’s formula W [ y 1 , y 2 ] ( t ) = C exp { − ∫ t 0 t p ( τ ) d τ } . Calculation: The given differential equation is, t y ″ + ( t − 1 ) y ′ + 3 y = 0 . Divide by t and simplify as, y ″ + ( t − 1 t ) y ′ + 3 t y = 0 y ″ + ( 1 − 1 t ) y ′ + 3 t y = 0 Comparing y ″ + ( 1 − 1 t ) y ′ + 3 t y = 0 with the general form y ″ ( t ) + p y ′ ( t ) + q y ( t ) = 0 gives p = 1 − 1 t

Mercedes-Benz stadium's soccer field is 115 yards in length × 75 yards in width. When Mercedes-Benz hosts a concert, the stage takes up the first 20 yds. The two VIP areas takes up the next 4 yards. After that, there are six ground floor sections. Each ground floor section is divided by aisles that are 5 yards wide. Each chair requires a square of 1 yard x 1 yard. Use the above information to answer the following questions: How many VIP ground tickets could you sell? How many additional ground tickets could you sell?
