Answer:
Annual Savings will be ;
Ordering Cost = $2,993.88
Holding Cost = $661.78
Explanation:
First Calculate the Economic Order Quantity (EOQ)
EOQ = √ 2 × Annual Demand × Ordering Cost per Order / Holding Cost per unit
    = √ ((2 × 783× 12 × $31) / ($11 × 32%))
    = 407
Note : Currently the firm orders at 783 crates per month
Savings in Ordering Cost will be :
Savings = Ordering Cost at Current Quantity - Ordering Cost at EOQ
       = (Total Demand / Current Quantity × Ordering Costs) - (Total Demand / Current Quantity × Ordering Costs)
       = (9396/783 × $31) - (9396/407 × $31)
       = $2,993.88
Savings in Holding Cost will be :
Savings = (Current Quantity - Economic Order Quantity) / 2 × Holding Cost per unit
       = (783 - 407) / 2 × ($11 × 32%)
       = $661.78
