12. Stretch Your Thinking Greyson is planning to lay a brick
driveway which will be made up of 84 rows of 14 bricks
per row. He will also lay a backyard patio with 25 rows
of 31 bricks per row. How many pallets of bricks should
Greyson order if each pallet has 1,000 bricks?
Show your work.
Greyson should order 2 pallets. The driveway
will need 84 × 14, or 1,176 bricks. The patio
will need 25 × 31, or 775 bricks. This is a total
of 1,951 bricks. So, he should order 2 pallets of
1,000 bricks each.
