Example to compares the $\frac{?}{{?}_{4}L},$EOQ, and POQ, lot sizing techniques

The Lifetime Sports Company has been using MRP to manufacture sports equipment for a number of years. Recently, Bob Banda, the operations manager, decided to investigate the use of lot sizing for MRP$-$generated orders. As a test case, Bob selected a typical product in their line of fishing rods and gathered weekly data over a month's time. Ordering costs are K$60$ per order, and carrying costs are K$1$ per unit per week. The beginning inventory is $30$ units, and lead time is one week. Help Bob determine whether the $L4L,$EOQ or POQ lot sizing technique is more appropriate
