Step 1 - Calculate the total weight of the drums
Number of drums times the weight of each drum = Total weight of all drums
{{numberDrums}} x {{drumWeight}} = {{numberDrums * drumWeight}}
Step 2 - Add the weight of the pallet to the total weight of the drums
Total weight of all drums plus the weight of the pallet = Total combined weight of the drums and the pallet
{{numberDrums * drumWeight}} + {{palletWeight}} = {{numberDrums * drumWeight + palletWeight}}
