Final answer:

Jillian's ending balance after five months with a 2% monthly interest rate is approximately $2208.16.

Step-by-step explanation:

To calculate Jillian's ending balance after five months with a monthly interest rate of 2%, we can use the compound interest formula: A = P(1 + r)^n, where A is the ending balance, P is the principal (initial balance), r is the interest rate per period (in decimal form), and n is the number of periods. In this case, P = $2000, r = 0.02, and n = 5. Plugging these values into the formula, we get: A = $2000(1 + 0.02)^5.

Calculating the expression inside the parentheses first, we have (1 + 0.02) = 1.02. Then, raising 1.02 to the power of 5, we find that (1.02)^5 ≈ 1.104081. Finally, multiplying $2000 by 1.104081, we find that Jillian's ending balance after five months with interest is approximately $2208.16.
