1. Suppose that a firm manufactures coffee machines and sells them for $170 each. The costs incurred during the production and sale of these machines are $566921 plus $59 for each machine produced and sold. How many coffee machines must be sold for the firm to break even?
2. A car company offers a base model that costs $20221 and gets 24 miles per gallon in the city. The company also offers a hybrid model that costs $25376 and gets 43 miles per gallon in the city. If the cost of gas is $2.96 per gallon, how many (city) miles would need to be driven in the hybrid model to make up the difference in cost?
