Commutative property means that you can rewrite the equation in a different order. So for example, if I have 3 + 8 + 5 I can rewrite it as 5 + 3 + 8 or 8 + 5 + 3 and so on and so forth. So, we must go over all the options to narrow it down. It isn't B or C, So lets look at D. D shows you 12 + 6 + 15 = 12 + 6 + 15 this is the wrong answer because it does not rewrite the equation. It just repeats itself so lets take a look at option A. A says 12 + 6 + 15 = 12 + 15 + 6 this is the correct answer because it rewrote the equation in a different order but they are still the same numbers.
So the correct answer is
A) 12 + 6 + 15 = 12 + 15 + 6

During a sale at the bookstore,books sold for $3 and magazines sold for $2.50.Jan spent $16 and bought a total of 6 books and ma

quester [9]

If you would like to know how many of each did Jan buy, you can calculate this using the following two equations:

b ... the number of books
m ... the number of magazines

$16 = b * $3 + m * $2.50 ... 16 = 3 * b + 2.50 * m
b + m = 6 ... b = 6 - m
__________________
16 = 3 * b + 2.50 * m

16 = 3 * (6 - m) + 2.50 * m

16 = 3 * 6 - 3 * m + 2.50 * m

16 - 18 = - 3 * m + 2.50 * m

- 2 = - 0.50 * m /0.50

m = 2 / 0.50

m = 4 magazines

b = 6 - m = 6 - 4 = 2 books

Result: Jan bought 4 magazines and 2 books.
