Final answer:
Kevin has $418 more money than Steven after 1 year.
Step-by-step explanation:
To calculate the difference in money Kevin has compared to Steven after 1 year, we need to calculate the interest earned by each brother. For Steven, he invested $19,000 in a savings account with an annual return of 2.7%. To calculate his interest, we multiply his initial investment by the interest rate: $19,000 * 0.027 = $513. For Kevin, he invested $19,000 in a CD paying 4.9% annually. Again, we calculate his interest by multiplying his initial investment by the interest rate: $19,000 * 0.049 = $931.
Now, we find the difference between the interest earned by Kevin and Steven: $931 - $513 = $418. Therefore, Kevin has $418 more money than Steven after 1 year.
