Let ’ s extend problem 3 to a 2 - day rather than a 1 - day wallet sale. On the second day, the storekeeper decides to repeat his change - the - price - every - two - hours strategy, but he drops each price by 10% from its amount on the first day. His sales in each 2 - hour period on the second day are 50% higher than they were on the first day.

(a) Create a table just like the table in problem 3, except use numbers for the second day.

(b) Using the same assumption about overhead as in problem 3, how much money did the storekeeper make or lose on the second day?
