88. Sales analysis. Repeat Problem 86 if S' ( t ) = 500 t 1/4 + 300 and all other information remains the same. Use a graphing calculator to approximate the solution of the equation S ( t ) = 20,000 to two decimal places. 86. Sales analysis. The rate of change of the monthly sales of a newly released football game is given by S ′ ( t ) = 500 t 1 / 4 S ( 0 ) = 0 where t is the number of months since the game was released and S ( t ) is the number of games sold each month. Find S ( t ). When will monthly sales reach 20,000 games?
