A farmer wants to hire workers to pick 900 bushels of beans. Each worker can pick 5 bushels per hour and is paid $2 per bushel. The farmer must also hire a supervisor at $10 per hour while the picking is in progress, and has additional costs of $8 for each worker hired. How many workers should he hire in order to minimize the total cost? What will be his total costs? Draw a graph of the cost function.
Not sure how to procede on this one. There seems to be some variables missing like, how long does he have to pick the beans (is it per day?). Based on the assumption, there only needs to be one but has to be at least one supervisor. So that ($10 + $8x)t for the cost of the workers and ($2*5)t profit. Not sure where to go from here.
