Alex earns a $35,000 salary in the first year of his career. Each year, he gets a 3% raise.
Which expression gives the total amount Alex has earned in his first n years of his career?

Step-by-step explanation:

Each year, he gets a 3% raise. It means that her salary in increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as

Sn = (ar^n - 1)/(r - 1)

Where

n represents the number of term in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

a = $35000

r = 3 + 3/100 = 1.03

Therefore, the expression that gives the total amount Alex has earned in his first n years of his career, Sn is

Sn = (35000(1.03^(n) - 1)/1.03 - 1

Sn = (35000(1.03^(n) - 1)/0.03

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
