The correct answer is:

32 pounds

Explanation:

She has 3 containers that hold 8 pounds each; 3(8) = 24 pounds of bird seed.

She has 6 containers that hold 12 pounds each; 6(12) = 72 pounds of bird seed.

This gives her a total of 24+72 = 96 pounds of bird seed.

She used 4 pounds of this; this gives her 96-4 = 92 pounds left.

She wants to use 30 containers that hold 2 pounds each; 30(2) = 60 pounds. This would give her 92-60 = 32 pounds left.

The amount of birdseed leftover is 32

The number of containers is:

\(\mathbf{Small = 3}\)

\(\mathbf{Large = 6}\)

The number of pounds is

\(\mathbf{Small = 8}\)

\(\mathbf{Large = 12}\)

So, the total number of pounds is:

\(\mathbf{Total = 3 \times 8 + 6 \times 12}\)

\(\mathbf{Total = 96}\)

From the question, 4 pounds were used.

So, the amount left is:

\(\mathbf{Amount = 96 - 4}\)

\(\mathbf{Amount = 92}\)

She wants to use 30 containers that contains 2 pounds each.

So, the left over is:

\(\mathbf{Left= 92 - 30 \times 2}\)

\(\mathbf{Left= 92 - 60}\)

\(\mathbf{Left= 32}\)

Hence, the amount of birdseed leftover is 32
