Question

The cost of producing x units in a manufacturing process is given by the function C(x)= 1.25x+65. the revenue obtained from selling x units is given by R(x)= 2.75x-0.0025x^2. determine the profit as a function of the number of units sold if P=R-C.

Answer 1

R(x)= (2.75x-0.0025x^2) -(1.25x+65)

Answer 2

is that all it's asking?

Answer 6

Answer 7

you have 1.25 x and 2.75x you can add

Answer 8

whats the e for?

Answer 9

oh it is sci notation

Answer 10

1.50*x-0.0025*x^2-65 here it is with out it :D

Answer 11

then?

Answer 12

that is all

Answer 13

oh ok. thanks!

Answer 14

wait

Answer 15

usually people like it in standard form in order of decrasing powers

-0.0025*x^2 + 1.50*x - 65

just rearrange

Answer 16

Remember it well because I got a feeling they gonna ask you to max the function you created lol.
