At Grain House, the bulk price for the grain Amaranth is $2.50 per pound, with a minimum purchase of 20 pounds (lbs). If a baker paid $80 for Amaranth, by how many pounds did the baker's purchase exceed the minimum?

Rationale

The baker's purchase exceeded the minimum by 32 pounds.

The bulk price for Amaranth at Grain House is $2.50 per pound, and the minimum purchase is 20 pounds. If the baker paid $80, they bought 32 pounds of Amaranth more than the minimum required.

A (12) YOUR ANSWER

This is incorrect because by multiplying 12 by the price per pound ($2.50), we get $30. This would mean that the baker only paid $30 for the purchase which is less than $80.

B (40) YOUR ANSWER

This is incorrect because it suggests that the baker bought 40 pounds of grain in total. However, since the price per pound is $2.50, 40 pounds of grain would have cost the baker $100, not $80.

C (24) YOUR ANSWER

This is incorrect because it suggests that the baker bought 24 pounds of grain in total. However, since the price per pound is $2.50, 24 pounds of grain would have cost the baker $60, not $80.

D (32) CORRECT

This is the correct answer. If the baker paid $80 for the grain, and the price per pound is $2.50, that means the baker bought 32 pounds of grain in total. Since the minimum purchase is 20 pounds, the baker's purchase exceeded the minimum by 12 pounds.

Conclusion

The baker's purchase exceeded the minimum by 32 pounds. The other choices do not correctly calculate the total pounds of grain the baker could have bought with $80 at the price of $2.50 per pound. Therefore, they do not accurately represent the amount by which the baker's purchase exceeded the minimum.
