Calc 1 question involving mins/max.
I don't have the question in front of me, so this is going from memory, but I think I have the essentials.
A person is building a rectangular garden with one side being a brick wall, and the rest being fencing. The total area is 1000sqft. The brick costs $30 per ft, the fencing is $10. Find the dimensions with the least cost.
This was on an exam I just took and I tried to model it four different ways and ultimately ran out of time. Please help!
