Question

Please help. I'm lost with this word Problem.

(Supply and demand) A manufacturer of calculators finds that the supply and demand are given by
S = 750p + 40,000
D = -400p + 132,000
(a) Find the equilibrium price.
(b) What is the number of calculators sold at this price?

Answer 1

S -750p = 40,000
D + 400p = 132,000
u know how to slove?

Answer 2

u want me solve?

Answer 3

I have no clue; i'm sorry

Answer 4

frist equqtiob time (-1)
= -S +750p = -40,000

-S +750p = -40,000
D + 400p = 132,000
Add-------------------------
1150p=92000

p = 92000/1150
p =80
plug p =80 find s

D + 400(80) = 132,000
D+ 32000 = 132,000
D= 132000-32000
D =1000,000
here your answer

Answer 5

frist equation time (-1)

Answer 6

If I deserve medal then give me one

Answer 7

Of course...so is the (b) at 1000,000

Answer 8

thank

Answer 9

Supply =1000,000
demand =80

Answer 10
