Question Stats:

68% (02:25) correct 31% (00:57) wrong based on 57 sessions
If a company sells S tons (1 ton = 1000 kilograms) of product A annually and charges B dollars per ton, what is the profit if it costs G dollars to manufacture a kilogram of product A and P dollars to ship it to the customer?

(A) b-1000g+1000p
(B) bs-\frac{g+p}{1000}
(C) (b-(g+p))*s
(D) \left(\frac{g}{1000}-(b+p)\right)*s
(E) \left(\frac{b}{1000}-(g+p)\right)*1000s

My Question: I believe this solution is wrong. The final answer has units of $/kg inside the parenthesis, multiplied by S which is in tons. If somebody sees something I don't, let me know. Also, the explanation is confusing since they say use$5/kg as B, but then divide B by 1000 in the final equation (which converts /ton to /kg). Another thing is the question doesn't say if the shipping cost is per ton or per kg. Overall, this is a confusing question, confusing enough to have a wrong answer, so should probably be thrown away or reworded.

I agree. There is clearly a problem with the question.

The best strategy with problems like this one is to pick numbers

Let's say we ship 10 tons at $5/kg and it costs$3 to manufacture and $1 to ship S = 10 B = 5 G = 3 P = 1 --> (B/1000 - (G+P))S My Question: I believe this solution is wrong.

Another thing is the question doesn't say if the shipping cost is per ton or per kg. Overall, this is a confusing question, confusing enough to have a wrong answer, so should probably be thrown away or reworded. I agree If they charge$B/ton this means they charge $B/1000 for kg. The company sells 10000 kg, or 1000S. Their profit for every kg sold is BS. The expenditures are (g + p) per kg X 10000kg or 1000S = (G + P)1000S The profit is BS - 1000S(G + P). Take 1000S in front and you get 1000S(B/1000 - (G + P)), which is slightly different than the answer:)) In the brackets you have the profit in$/KG and you multiply this by KG to get $.

Answer: The best strategy with problems like this one is to pick numbers. Let's say we ship 10 tons at$5/kg and it costs $3 to manufacture and$1 to ship

S = 10, B = 5, G = 3, P = 1

(B/1000 - (G+D))S, So answer E

My question:

Doesn't 1000kg = 1 ton? Why isn't that equality placed the question...would it be like that on the actual test?
Now, if that is true, then the answer is saying that the profit will be:
S tons ($B/1000 kg- not tons) - ($g/km + p$/km) How are we using inequal measures in this equation? I came up with: S tons *$b/ton - ((S tons *1000g) + (S tons * 1000P)), so

Sb - 1000gs - 1000ps = profit.

2000 LBS = 1 ton

1kg=2.2 lbs (approx.)

1000kg = 2,200 lbs (approx)

u should get a note (1 ton = 1000 kilograms) in the question. IF not then the question is not clear enough what kind of ton they r referring to - imperial or metric.

Yes, but did you answer it correctly? What I'm saying is that in spite of the equality excluded from the question, I feel that the answer is incorrect because tons and meters have not been changed.

I believe this question hasn't been edited to reflect the right wording.

I think all you need to add to the wording is(in red ): If a company sells s tons of product A annually and charges b dollars per ton, what is the profit per kilogram if it costs g dollars to manufacture a kilogram of product A and p dollars to ship it to the customer?

OR

Edit the answer choice to have one that states:

S*(b - 1000*(g+p))

One small doubt, is P the cost of shipping 1 kg or 1 Ton or S Ton of material?

Scanning through the answer it seems as though E would be the only feasible one because it takes into account the difference between the profit per ton and the two cost per 1000 units.

selling price = number of tons * cost per ton = sb
cost of manufacturing S tons = 1000 gs
cost of shipping S tons = 1000 ps

Profit = Seppling price - cost price = sb -1000s(g+p) = 1000s (b/1000 - (g+p))

ok so I read this totally different.....If a company sells S tons (1 ton = 1000 kilograms) of product A annually and charges B dollars per ton, what is the profit if it costs G dollars to manufacture a kilogram of product A and P dollars to ship it to the customer?

Does P dollars to ship automatically mean P dollars be ton.....I read it as P dollars total. which would change the answer totally.

Answer E also, by taking P as the cost to ship a kilogram of product A

I think that per kilogram should be added after p dollars to clarify. I had gone for p as the overall shipping cost but realised that it has to be per kg when i saw the choices.
