Bunny Helpers, Inc., has just received an order for $100$ Deluxe Easter Baskets, which must be ready for delivery at the start of week $6.$ An MRP planner has prepared the following table showing product structure, lead times $($orders are lot$-$for$-$lot$),$ and quantities on hand:

Each Deluxe Basket contains two dark chocolate truffles and four carved chocolate eggs; additionally one bottle of Alka$-$Seltzer is included for those who overindulge.

If the firm is using a fixed$-$period lot size of two periods, what is the order size for the first order?
