Question 13 (1 point)

Answer 1

Answer:

$S(x)=42,000*(1.04)^{x}$

Step-by-step explanation:

We have as data

a = $42,000 (salary during the first year)

x = number of years

i = 4% = 0.04 (annual increase interest)

S(x) = Salary based on the years elapsed

"a" and "i" are constant for each year, while "x" increases one each year.

The function S(x) can be calculated like this:

$S(x)=a*(1+i)^{x}$

Substituting constant values, we have

$S(x)=42,000*(1+0.04)^{x}$

Simplifying, we have

$S(x)=42,000*(1.04)^{x}$

Hope this helps!

 

Answer 2

Answer:

S(x)=42000 * 1.04^x

Step-by-step explanation:

now = 42000

in 1 year = 42000 *1,04, because 4% increase is to multiply 1,04

in 2 years = 42000 *1,04*1.04 = 42000*1.04^2

in x years = 42000 * 1.04^x
