Question

Its marketing people estimate that at a price of p dollars, it can sell a total of
q = 260,000 − 10,000p
copies. What price will bring in the greatest revenue? guys i need help asap my mom wants me to answer this problem before i go to bed plz!!!!!

Answer 1

someone needs to help me

Answer 2

Revenue = (# of items sold)*(price per item)

Revenue = q*p

R = (260,000 − 10,000p)*p

R = 260,000p − 10,000p^2


The next step is to find the vertex of that quadratic. I'll let you take over.

Answer 3

dude you gotta help me @jim_thompson5910

Answer 4

are you able to graph?

Answer 5

yes but what am i suppose to graph?

Answer 6

R = 260,000p − 10,000p^2

or

y = 260,000x − 10,000x^2

Answer 7

what does that ????? mean?

Answer 8

refresh the page

Answer 9

the symbols get weird, idk why

Answer 10

is it 260000x times 10000x^2

Answer 11

minus

Answer 12

y = 260,000x - 10,000x^2

or

y = -10,000x^2 + 260,000x

Answer 13

but there is no vertex?

Answer 14

@jim_thompson5910

Answer 15

there is, you just need to have the right window

Answer 16

do i enter both equations?

Answer 17

you can also use the formula

x = -b/(2a)

a = -10,000 and b = 260,000 in this case

Answer 18

omg thank you so much

Answer 19

Marketing estimates that at a price of p dollars, it can sell
q = 300,000 − 15,000p
copies, but each copy costs $4 to make. What price will give the greatest profit?

Answer 20

@jim_thompson5910 can you give me another equation for this one
