I am suppose to solve for g... I simply don't understand where I'm going wrong. I know that I need to divide at some point at the end in order to solve for g, but I can't for the life of me figure this out... This is what I've done:

(205000000/225000000)*225000000g-(13000000/225000000)*225000000g-.0889(225000000(1+g))*(1-.50)
.09111*225,000,000g-.0578*225,000,000g-.0889*225,000,000(1+g)*.5
0.005266158*50625000000+16g^2-.0889*225000000(g+1)*.5
0.005266158*50625000000+16g^2-.04445*225000000g+4445*225000000*.5
0.005266158*50625000000+16g^2-.04445*225000000g+5000625
266,599,249+16g^2-.04445*225000000g+5000625
271599874+16g^2-10001250g

CAN ANYONE POINT ME IN THE RIGHT DIRECTION? Not asking for the answer, just guidance on the equation... :?

Where is the equal sign? That's not an equation.

And (205000000/225000000)*225000000 = 205000000 ; you didn't know that?!
 
Please don't be mean... I haven't done algebra in 15 years... and I've been working on a project for 2 1/2 weeks and I'm exhausted and almost finished, however I'm stuck. I simply need guidance. I can add and = 0 because the problem stated to set that variable to 0. I know that I don't need to balance the equation, I simply need to solve for g and I'm lost.
 
It was a HUGE word problem where I needed to substitute the variables and solve for g... I have substituted ALL the variables and just need guidance on the steps to take to solve.

It is to be regretted if the necessity for information has offended you, but asking what the actual question was is not "mean". Until we know what the question, there is little way for us to determine what might possibly be the correct solution.

Which means that you have two and a half weeks' familiarity with the context which generated the posted expression. We have no idea where it came from, to what it might apply, or even if it is correct. We don't know why the fractions have not been simplified. For instance, why has the very first fraction not been simplified to 205/225 and then to 41/45? Presumably, you have a good reason for this choice, but we don't know what that is.

Respectfully, it is difficult to advise without any information.

There is no equation, so there's nothing to solve. You have been given the value of the variable (according to your statement above), so there is nothing to solve for, even were there an equation. As such, I'm a bit confused as to what "equation" you have in mind (but haven't posted), and why you're wanting to "solve" for a value you say you've been given...?

Please reply with the requested clarification. Thank you.

Eliz.
 
Ok... I may have it...
Does this look correct?

(205000000/225000000)*225000000*g-(13000000/225000000)*225000000*g-.0889(225000000(1+g))*1-.50
205000000g-13000000g-.0889(225000000(1+g)*.50
192000000g-20002500+20002500g*.50
192000000g-20002500+10001250g
202001250g-20002500=
202001250g-20002500+20002500=20002500
202001250g=20002500
202001250g/202001250=20002500/202001250
g=.0990
 
I need to find g (growth rate, a percentage) it is simply a financial formula, but I knew I needed to remember my algebra to solve... and I was not referring to the "clarity" question as being mean, rather than Denis's condescending remark "You didn't know that?" People are on here for help...

The material that you were referring to that I supposedly needed to be familiar with was NOT algebra... it was finance... and I simply needed some guidance to remember my algebra in order to solve... but that's okay, I'm smart enough, I think I've figured it out on my own...
 
OH... and Elizabeth, if you read through the entire posts.... someone asked about an = sign for the equation. The variable set to 0 was the one AFTER the =... NOT g. "g" is what I needed to solve for.
 
So your equation is:
(205000000/225000000)*225000000g - (13000000/225000000)*225000000g - .0889(225000000(1+g))*(1-.50) = 0

Start by dividing each term by 5000000:
(41/45)*45g - (26/45)*45g - .0889(45(1+g))*(1-.50) = 0
Next, simplify:
41g - 26g - .0889(45 + 45g)(.5) = 0
Simplify last term:
41g - 26g - .04445(45 + 45g) = 0
Continue:
15g - 2.00025 - 2.00025g = 0
12.99975g = 2.00025
g = 2.00025 / 12.99975 = .15386834.....

Hope that helps. And if you think I was being "condescending", that's up to you: you control your own thinking.
