I assume you know that

S= 49

H= 0.2Qu

D=5000

Where u is the unit price

Find Q for each unit price and then find the total annual cost for each EOQ at those unit prices.

If the EOQ for unit price £5 is 1100 it is outside the order range so just choose the quantity to be the nearest limit of the order range (so the EOQ for unit price £5 would be 999)
