What steps do I take to finding the answer to this question?
Two facilities process an average of 15 million pounds of aluminum each month. How many pounds of aluminum do the Ohio smelting plants average per week?
First, clarify the question. Does it mean:
a) two facilities ... each month each, or in total?
b) If it's "each", then no problem, 15 million a month is 15 million divided by number of weeks in a month to get the number per week.
c) If it's "in total" then you have to make the assumption that the processing power of each one is equal to that of the other. Otherwise you don't know where to start. If they do have equal processing power, then divide the answer in (b) above by two.
d) You have to assume that the "Ohio smelting plants" is one of those "facilities" that's being talked about.
Is this the complete question? If so, then the book you got it out of is rubbish. Wipe yourself with it. If not, and it's been set by the teacher, reboot it.
Yes, then divide by .
EDIT: This will give the aluminium (in million pound) produced by the two facilities combined. If Ohio smelting is one facility and you are asked to find the amount produced by itself, then assume that that the facilities produce equal and divide the answer by two.
Yes, that is what I said I obtained in my earlier post:
