Suppose a three-period weighted average is being used to forecast demand. Weights for the periods are as follows:
wt-3 = 0.2, wt-2 = 0.3 and wt-1 = 0.5.
Demand observed in the previous three periods was as follows:
At-3 = 2,200, At-2 = 1,950, At-1 = 2,050.
What will be the demand forecast for period t?

A) 2,000 B) 2,095 C) 1,980 D) 2,050 E) 1,875

Jamie is saving for a trip to europe. she has an existing savings account that earns 3 percent annual interest and has a current balance of $4,200. jamie doesn’t want to use her current savings for vacation, so she decides to borrow the $1,600 she needs for travel expenses. she will repay the loan in exactly one year. the annual interest rate is 6 percent. a. if jamie were to withdraw the $1,600 from her savings account to finance the trip, how much interest would she forgo? .b. if jamie borrows the $1,600 how much will she pay in interest? c. how much does the trip cost her if she borrows rather than dip into her savings?
