The best answer to the question that is being stated above would be that A and B are both dependent. If I was told that P(A | B) = P (B | A), then the true statement is that both variables inside would be dependent upon each other, no matter if you exchange their places with one another.

Answer:

Dawn has $1670 in account 1 and $1570 in account 2.

Step-by-step explanation:

Dawn can multiply the second equation by 8 and add 7 times the first equation.

8(3/8A +7/8B) +7(A -B) = 8(2000) +7(100)

10A = 16,700

A = 1670

B = 1570 . . . . 100 less than A

Dawn has $1670 in account 1 and $1570 in account 2.

<em>Check</em>

3/8(1670) +7/8(1570) = 626.25 +1373.75 = 2000
