Costs that stay relatively the same, such as paying for rent or salaries of managers are referred to as _____________ costs. Costs that fluctuate, such as paying the wage for a part-time employee for a seasonal position at Blue Mountain, are called ______________ costs. Fixed and variable costs can also included _____________ costs, which are the amount it takes to run a facility—including the wages of all employees and paying for the electric. When you add fixed and variable costs (which already include the operational costs), the result is the _________ costs. When a company is determining the cost of producing one more unit of a good, this is referred to as the _______________ costs.

For example, if a worker can generally make 10 jeans per hour, and you have 2 people working, how many jeans could your company produce? _______. When you hire one more person, generally, you want to ______________ your output—this is referred to as ___________________ marginal returns. Using the above example, if you added a 3rd person and each person was now only able to make 9 jeans per hour, what is the total jeans per hour your company could produce? __________ Although the output with a 3rd person is greater than it was only 2 people, each person is making less per hour; this is called __________________ marginal product of labor. Businesses are extremely careful when hiring individuals because they do not want _________________ marginal returns to occur—when they hire too many people and everyone gets in the way of each other. For example, if you would hire a 4th person, each person may only be able to produce 3 jeans per hour. How many total jeans could they produce? _________ Page 16 Multiplying the quantity sold by the amount sold will equal ________________________. For example, if you sold 10 bottles of water (quantity), each for $2 a bottle, what is your total revenue? _____ A firm’s basic goal is to maximize ______________.
