Answer:

The hint in this problem is the word "about" or approximately how many pounds. So we could find the solution by estimation through rounding off. We know that almonds cost about 3.50 per pound and a bag costs about $7.00. Dividing 7 by 3.50 per pound, will give us $7 ÷ $3.50 = 2 pounds.

The answer is 2 pounds.
