I need help on this!!
olga nikolaevna [1]

Answer:

Commutative

Step-by-step explanation:

Given

3 + b + 2 = 3 + 2 + b

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

a + b = b + a

So:

3 + b + 2 = 3 + (b + 2)

When the positions of 2 and b are interchanged, we have:

3 + b + 2 = 3 + (2 + b)

Remove bracket

3 + b + 2 = 3 + 2 + b

EQUATION:

Least Paid / 12  =====>  23.04 /12

Most Paid / 12  ======>    29.40 / 12



Divide:

23.04 / 12    =     1.92 / LB

29.40 / 12     =     2.45 / LB

Now Subtract:

2.45   -     1.92

Answer   ======>    0.53 is the difference, between the greatest price per round, and least price per round of butter the cook would have paid within the last year.
