A manufacturer grows oranges which are used to produce orange juice and orange marmalade. One orange gives 1 unit of orange juice AND 2 units of marmalade. Assume that the cost function of growing oranges is given by C(q)=0.05 q2 (and assume that there are no further costs of production). Demand for orange juice is given by qJ = 25 – 50 pJ and demand for marmalade is given by qM = 100 – 50 pM where pJ and pM denote the prices for orange juice and marmalade respectively. How many oranges should the manufacturer grow and what prices should she set for marmalade and juice? Assume that disposal is free.

Shorter and more consistent. Binary or base two system only allows zeros and ones, for example the number 255 in decimal system is equivalent to eight ones in the binary system. Hexadecimal numbers contain the digits 0 to 9 as well as the letters a to f, making it easier to deal with large decimal or binary numbers.

When working with numbers, it is important to understand the concept of narrowing; this happens when a variable of a smaller type is initialized with a larger type. As we store a smaller number in the larger memory space, we don't have to worry about data loss as the additional bytes in memory are filled with zeroes. Although these numbers are not truly random, they are based on some kind of mathematical formula. To generate random numbers, we can use the 'srand' (seed rand) function, which will give us two random values between one and six. To limit the range of this random number, we can use the formula shown onscreen; though this method is more complicated and not suitable for beginners, it is still a good way to learn how to generate random numbers - for example, to roll a dice.

Now, suppose the inverse market demand function for a two-firm Stackelberg model is given by P=49-Q where Q=q1+q2 is the total output produced in the market, P is the market price, q1 is the quantity of output produced by firm 1, q2 is the quantity of output produced by firm 2. Firm 1 is the leader and firm 2 is the follower. The marginal costs of the two firms are MC1=2 and MC2=3.
