Help!!!??? The US Maritime Administration estimated that the cost per ton of building an oil tanker could be represented by the model y=113,000/x+235, where y is the cost in the dollars per ton and x is the tons(in thousands). What size of oil tanker (in thousands of tons) can be uilts for $200 per ton?

Question

hero · Answer

Hint: y = 200

anonymous · Answer

Do I just divide 113,000?

hero · Answer

You have to solve for x

hero · Answer

200 = 113,000/x + 235

anonymous · Answer

then do I multiply it?

anonymous · Answer

$$200=\frac{ 113000 }{ x+235 }$$

hero · Answer

So, yes multiply both sides by x + 235

hero · Answer

Let me know what you get afterwards.

anonymous · Answer

200x+47000=113000+26555000

anonymous · Answer

But solving it that way just got me x=-235

hero · Answer

That can't be right

anonymous · Answer

I know...now I'm just confused

hero · Answer

That's not the right value for x

hero · Answer

x is positive anyway

anonymous · Answer

Yes, I know that, but now I'm not sure how to get x

hero · Answer

Yeah, you messed up while solving for x somehow.

anonymous · Answer

Well I told you what I got when I multiplied both sides....was that wrong?

hero · Answer

(x + 235)/(x+235) should have cancelled on the right side.

hero · Answer

Leaving you with just

200x+47000=113000

now finish solving for x

anonymous · Answer

Ohh, I see what I did wrong. Thank you!

anonymous · Answer

There is also one equation that I just can't figure out.
