10 + 2Q = 10 + Q + 100/Q

so Q = 10

How do i reach 10 the 100/Q part is confusing me.

Thanks.

I suspect i am in the wrong section sorry about that.

Hang on, just so we're clear, is this your equation: $\displaystyle \begin{align*} 10 + 2Q = 10 + Q + \frac{100}{Q} \end{align*}$ ?

its 10 + 2Q = 10 + Q + 100/Q and i need to solve for Q Basically its for a businesses marginal cost = average total cost. in order to minimize costs mc=atc

500/q + 20q= 40q

Therefore,

q= 5

another same type... don't understand the divide. - Apr 29th 2014, 08:49 AMJeffMRe: need help with algebra equation
I do not understand your last question. You are going to get a term divided by q whenever you are computing average costs and total costs has a component of fixed costs. You can see why if you look at the answer I gave to your prior question (which unfortunately I could not answer within the time frame that you needed). Or are you asking how to solve this type of equation? Please remember that you have to make your questions comprehensible to us; we are not mind readers.
