First, set up your proportion. $2.88 goes to 1 lb, while x amount of money goes to 3.5 lbs.
Second, cross-multiply. When you cross-multiply, you multiply the top term of the left side by the bottom term of the right side, then vice versa. Multiply 2.88 with 3.5, then multiply 1 by x.
Now, we have 10.08 = x. We don't need to do any simplifying here because x is already by itself.
Final answer: 3.5 lbs of almonds cost $10.08
