Final answer:
A 5% raise each year for four consecutive years is equivalent to a 20% raise overall.
Step-by-step explanation:
The statement in the question is true.
To understand why, let's look at the calculations. If you receive a 5% raise each year for four consecutive years, the total raise over the four years would be:
5% + 5% + 5% + 5% = 20%
This means that a 5% raise each year is equivalent to a 20% raise overall.
