A 135-kg steer gains 3.5kg/day and costs 80 cents/day to keep. The market price for beef cattle is $1.65/kg, but the price falls by 1 cent/day. When should the steer be sold to maximize profit?
Revenue= (Price/units)(#of units)
Cost=(cost/unit)(# of units) + set costs
show the revenue and costs.
put in vertex form.
135kg +3.5kg/day*x =weight
set the derivative to 0 to find max profit
hope this helps
