Tobin Fisheries currently sells to its customers on terms of $\frac{3}{10},$ net $30.$ Its average collection period is $20$ days, with $80$ percent currently taking up the discount. All sales are credit sales. Upper management has expressed concern about sluggish sales, and the marketing department would like a more attractive credit package. Next year's sales are projected to be $$2\mathrm{.}19$ million. It has been estimated that with terms of $\frac{4}{15},$ net $45,$ sales next year would jump to $$2\mathrm{.}92$ million and $65$ percent of sales would take the discount, but the average collection period would increase to $42$ days. Tobin's contribution margin of $6$ percent would hold with the expansion of sales, as would its short$-$term financing cost of $10$ percent.

Q$10$: The incremental sales discount is:

$$75,920$

$$23,360$

$$21,900$

$$56,940$

$$52,560$
