Question

A masonry worker needs 10000 bricks for a new project. On average no more than 7% of a load of bricks are damaged on delivery. If the bricks are delivered on pallets of 100, what is the least amount of bricks that he should order so that there are enough bricks to finish the job. Give your answer to the nearest hundred bricks.

Answer 1

To account for the 7% of damaged bricks, the masonry worker should order 107% of the needed amount of bricks.

10000 bricks * 1.07 = 10700 bricks

Since the bricks are delivered on pallets of 100, the masonry worker should round up to the nearest pallet:

10700 bricks / 100 bricks per pallet = 107 pallets

Therefore, the masonry worker should order at least 10700 bricks to ensure there are enough bricks to finish the job.
