Mathematics Homework Help

I’m working on a mathematics question and need an explanation to help me learn.

(2) If the Supply Function for a product is Qs = Qs (P), where Qs is the quantity Supplied and P is the Price of the good.

If Qs (P) = 13,000 + 2,000P, Evaluate Qs (6),  Qs (10) and Qs (5).

QS (6) = 13,000 + 2,000(6) = 25,000

QS (10) = 13,000 + 2,000(10) = 33,000

QS (5) = 13,000 + 2,000(5) = 23,000

If Qs (P) = 15,000, what is P?; If Qs (P) = 24,000, what is P?

????????????????

(3) If the Demand Function Qd of the same product in #2 is Qd (X) = 28,000 – 1000P.

Evaluate Qd (7), Qd (9);

Qd (7)= 28,000 – 1,000(7) = 21,000

Qd (9)= 28,000 – 1,000(9) = 18,000

If Qd = 15,000, what is P

???????????????
