A carpet manufacturer makes four kinds of carpet on a machine. For simplic- ity, call these four types of carpet, A, B, C, and D. It takes 3 hours to switch production from one type of carpet to another. The demand rates (yards/hr) for the four types of car- pet are as follows: 100, 80, 70, and 50. When producing, the machine can produce at the rate of 350 yards/hr. Batch sizes are chosen to minimize inventory while also satisfying the demand requirements. The manufacturer produces with a schedule that cycles through each of the four types, (e. g., A, B, C, D, A, B, ...). a. What batch size (yards) is chosen for carpet type A? [5.6) b. Suppose they produce 16,800 yards of carpet A in each production cycle (and 50,400 yards of carpet in total within the production cycle). What would be the average inven- tory of carpet A?

Suppose you win a small lottery and have the choice of two ways to be paid: you can accept the money in a lump sum or in a series of payments over time. if you pick the lump sum, you get $2,950 today. if you pick payments over time, you get three payments: $1,000 today, $1,000 1 year from today, and $1,000 2 years from today. 1) at an interest rate of 6% per year, the winner would be better off accepting the (lump sum / payments over time), since it has the greater present value. 2) at an interest rate of 9% per year, the winner would be better off accepting the (lump sum / payments over time), since it has the greater present value. 3) years after you win the lottery, a friend in another country calls to ask your advice. by wild coincidence, she has just won another lottery with the same payout schemes. she must make a quick decision about whether to collect her money under the lump sum or the payments over time. what is the best advice to give your friend? a) the lump sum is always better. b) the payments over time are always better. c) it will depend on the interest rate; advise her to get a calculator. d) none of these answers is good advice.
