If they continue to earn a 3% increase in their annual salary, what statement could describes the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year.

A. The expression 1.03^5n can be used because (1.03^5)^n = 1.03^5n
B. The expression 1.03^5n can be used because 1.03^5 * 1.03^n = 1.03^5n
C. The expression 1.03^5+n can be used because 1.03^5 * 1.03^n = 1.03^5+n
D. The expression 1.03^5n can be used because 1.03^5 + 1.03^n = 1.03^5+n

Answer 1

B. The expression 1.03^5n can be used because 1.03^5 * 1.03^n = 1.03^5n

C. The expression 1.03^5+n can be used because 1.03^5 * 1.03^n = 1.03^5+n

D. The expression 1.03^5n can be used because 1.03^5 + 1.03^n = 1.03^5+n
