$0.25 per pound.

Step-by-step explanation:

Let us find unit rate for both quantities.

Therefore, cost of per pound for first given rate is $3.5.

Now let us find unit rate for second quantity.

Therefore, we will save $0.25 per pound by buying the least expensive.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
