Product A:P = .42 (R) - $26,440

Product B:P = .50 (R) - $58,190

Where R is revenue. Budgeted revenue for the two products are $86,000 and $95,000, respectively. Avoidable fixed costs for the two products are $16,393 and $32,004, respectively.

The company is considering dropping Product B because it appears to be losing money. If it does, the resulting freed-up resources can be used to increase revenue from sales of Product A by $36,000, but that will require $2,800 of additional fixed costs.

If X Company drops B and increases revenue from A, firm profits will change by ?

I need help on this budgeted profit function for two products.
