Question

On Monday, Elsbeth’s bank account balance was -$16.75. On Tuesday, she deposited a check for $5.72. On Thursday, she deposited $16.75. What is her new balance?

-16.75 + (5.72 + 16.75)

Use the commutative property to get:

-16.75 + (16.75 + 5.72)

Use the associative property to get:

(-16.75 + 16.75) + 5.72

On Friday, Elsbeth deposited her pay check for $872.56. What was the account’s final total?
A. -$866.84
B. $878.28
C. $895.03
D. $903.10

Answer 1

$5.72 - Thursday's balance

$878.28 - Final total

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

~Hope this helps!~
