Windsor Company has recorded bad debt expense in the past at a rate of 1.5% of accounts receivable, based on an aging analysis. In 2020, Windsor decides to increase its estimate to 2%. If the new rate had been used in prior years, cumulative bad debt expense would have been $360,100 instead of $270,075. In 2020, bad debt expense will be $130,800 instead of $98,100. If Windsor’s tax rate is 30%, what amount should it report as the cumulative effect of changing the estimated bad debt rate? (Do not leave any answer field blank. Enter 0 for amounts.)

Until recently, hamburgers at the city sports arena cost $4.70 each. the food concessionaire sold an average of 13 comma 000 hamburgers on game night. when the price was raised to $5.40, hamburger sales dropped off to an average of 6 comma 000 per night. (a) assuming a linear demand curve, find the price of a hamburger that will maximize the nightly hamburger revenue. (b) if the concessionaire had fixed costs of $1 comma 500 per night and the variable cost is $0.60 per hamburger, find the price of a hamburger that will maximize the nightly hamburger profit.
