Hello Mark, Thank's for replying. Here is my new attempt: LET x1 =represent the number of Cuban coffee sold LET x2 =represent the number of Colombian coffee sold R(X) = $5.50x1 + $3.80x2 C(x) = $1450 + 0.95x1 + 0.95x2 P(x) = R(X) - C(X) P(X) = 5.50x1 + 3.80x2 -1450 - 0.95x1...

Hi GIB Z, I didn' t pay attention to that, however looking at the question requirements it states that the answer needs to be to the rearest whole. Thus, I will use e^-1 = .3678794412, to get to P(2500) = $9798 NOW, for part (b), how do you get the amount of e^? I looked at a table that...

Here is my new attempt: I would appreciate if someone can check my answer: P(x) =15500(1-e^-0.0004x) evaluate at x=2500 15500(1-e^-0.0004(2500)) 15500(1-e^-1) e^-1=0.3678 P(2500) = 15500(1-0.3678) 15500-5700.9 P(2500) = $9,800 b) 12,000=15500(1-e^-0.0004x) 12,000/15500 =...

Hi Gib , You've made my day, it is true, I can't believe it. I will attempt it right away and post my answer. Thank you so much

Homework Statement A speciality coffee shop sells Cuban coffee beans for $5.50 each bag and Colombian coffee beans for $3.80 a package. 1.If the cost of sales is $1450 plus $0.95 per bag, write down the function which calculates the profit in terms of the number of bags of coffee beans sold...

Homework Statement A company's profit , in dollars, as a function of the number of items sold, x, is described by: Homework Equations 15500(1-e^-0.0004x) Calculate the profit when x=2500 units The Attempt at a Solution I am having a lots of problems with this one, but here is...

Thank you for replying. I followed your advised and here is what I got: f(x)=g(x) 10+3x-x^2=3x^2-6x-5 10+3x-x^2-3x^2=3x^2-3x^2-6x-5 10+3x-4x^2= -6x-5 10+3x-4x^2+6x=-6x+6x-5 -4x^2+3x+6x+10=-5 -4x^2+9x+10=-5 -4x^2+9x+10+5=-5+5 -4x^2+9x+15 =0 Applied the quadratic formula and got: x...

Sketch the function:? Hello everyone, I was asked the following question: On the same axes, sketch the functions: f(x) = 10+3x-x^2 g(x) = 3x^2-6x-5 Calculate the coordinates of the two points where the two lines cross. How far apart are the two points: I don't even know how to start...

Thank you very much, I understand now.

Linear inequalities! I need help solving the following inequality: ABS value(7x-8) <=4x+7 +/-(7x-8) <=4x+7 7x-8 <=4x+7 -(7x-8) <=4x+7 7x-8-4x <=4x+7-4x -7x+8 <=4x+7 3x-8<=7 -7x+8-4x <=4x+7-4x...

Thank you everyone, I was confused, but with your help found the solution to this problem

I have been trying to solve this problem for a whole week without success, I need help. Solve the following for x,y and z: 2x+5y-z = 18 7x-y+4z = 22 6x+2y-3z = 0.1x + 0.2y + 0.3z I have already combined all the terms of eq.#3 and equal it to zero, but it didn't work. I also...
