in a mixing bucket. She spills 13 pounds of the mixture while stirring the contents. The
mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of
mixture, and the leftover mixture is washed out of the mixing bucket
What is the greatest number of bricks Lynn can make?
bricks

How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest
number of bricks?
pounds​

Answer 1

Greatest number of bricks Lynn can make is 10 and 4 pounds of the mixture will be washed out of the bucket

Pounds of water = 39

Pounds of brick dust = 48

Total mixture = 87 pounds

Mixture spilled = 13 pounds

Mixture remaining = 87 pounds - 13 pounds

= 74 pounds

Mixture in each brick holes = 7 pounds of mixture

Greatest number of bricks Lynn can make = Mixture remaining ÷ Mixture in each brick holes

= 74 pounds ÷ 7 pounds

= 10 remaining 4 pounds

Therefore,

Greatest number of bricks Lynn can make is 10 and 4 pounds of the mixture will be washed out of the bucket
