Answer
X= 20.5
Work Step by Step
66x+147=1500
66x+147-147=1500-147
66x=1353
66x\66=1353/66
X= 20.5
Since the result has a decimal if we round it up and make it 21 then the total weight is gonna become 147+(66*21)= 1,533 pounds which exceed the maximum weight limit of 1,500 pounds.
Then the clerk should move 20 whole boxes each time in order not to exceed the maximum weight limit so 147+(66*20)=1,467 pounds.
