Final answer:
After 30 years, Alexx will have $12,405.18 and Spenser will have $12,304.36. Therefore, Alexx will have $100.82 more than Spenser.
Step-by-step explanation:
To determine how much more Alexx will have than Spenser after 30 years, we need to calculate the compound interest earned by each of them. Alexx's initial investment of $5,000 will grow over 30 years at a rate of 5% per year, while Spenser's investment in a retirement fund will grow at a rate of 4.75% per year. After 30 years, Alexx will have:
$5,000 * (1 + 0.05)^{30} = $12,405.18
Similarly, Spenser will have:
$5,000 * (1 + 0.0475)^{30} = $12,304.36
Therefore, the difference between Alexx and Spenser's balances after 30 years is:
$12,405.18 - $12,304.36 = $100.82
