B)499.05
C)1,149.05
D)2,384.59

B

Step-by-step explanation:

Starting balance is $557.83.

Deposited checks adds to the beginning balance

557.83 + 882.84 = 1440.67

Cash withdraw subtracts from the new balance

1440.67 - 325 = 1115.67

Checks paid by the bank subtract from the new balance

1115.67 - 617.77 = 497.90

Interest gets added onto the new balance

497.90 + 1.15 = 499.05

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
