Final answer:
After 30 years, Plan B will have made Mike the most money with a total of $287,150.
Step-by-step explanation:
To determine which plan will have made Mike the most money after 30 years, we need to compare the total amount of money he would earn under each plan.
Plan A): Mike receives a $5,000 raise every year.
So, after 30 years, he would have earned:
$50,000 + ($5,000 * 30) = $50,000 + $150,000
= $200,000
Plan B): Mike receives a 6% raise every year.
To calculate his salary after 30 years, we need to calculate the compound interest on his initial salary:
$50,000 * (1 + 0.06)^30 = $50,000 * 5.743
$287,150
So, Plan B will have made Mike the most money after 30 years, with a total of $287,150.
