b. $878.28
c. $895.03
d. $903.10

$5.72 - Thursday's balance

$878.28 - Final total

Step-by-step explanation:

Commutative property - States that you can move numbers around without affecting the sum.

-16.75 + 5.72 + 16.75

5.72 - 16.75 + 16.75                                = $5.72

5.72 + 16.75 - 16.75

Associative property - States that you can regroup numbers without affecting the sum.

-16.75 + (5.72 + 16.75)

(-16.75 + 5.72) + 16.75                              =$5.72

$5.72 + $872.56  = $878.28
