setting up Linear Equation?
A mining company can extract 2000 tons of gold ore per day with a purity of 3 ounces of gold per ton. The cost of extraction is $1000 per ton. If p is the price of gold in the dollars per ounce, find a function that gives the daily profit/loss of the mine as it varies with the price of gold. What is the minimum price of gold that makes the mine profitable?
Would it be 1000=3x-2000
Is that right?
Thanks

Well, it depends what form you want this in.
There's slope-intercept, point-Slope, and standard form.
Slope-intercept:
Y=mx+b
Point slope: (this is hard to type)
Y-Y*=m(x-x*)
The asterisks are subscripts of 1
And standard form:
Ax+by=c
Now, I can't really help too much on the problem itself, I haven't taken Algebra 1 since 6xth grade. --and I'm a junior in high school.
