Niah works as a retail sales clerk earning $18,000 per year. she plans to go to school for medical billing that has a median salary of $35,000. the cost of her education will be $20,000. if niah does not work for the 2 years that she is in school, about how long will it take her to recover her investment if she gets a medical billing job making the median salary when she graduates? a. less than 1 year b. 1.2 years c. 1.6 years d. 3.3 years

d. 3.3 years

Step-by-step explanation:

Let x represent number of years to recover Niah's investment.

We have been given that Niah works as a retail sales clerk earning $18,000 per year.

Amount earned in x years, working as clerk would be .

The amount earned in two years working as clerk would be .

We are also told that Niah will get a median salary of $35,000 after doing the course.

So amount earned in x years doing medical billing job would be .

Since the medical billing course costs $20,000, so total amount Niah would have lost or invested in medical billing job would be .

Now, we will equate both amounts and solve for x as:

Therefore, it will take Niah approximately 3.3 years to recover her investment if she gets a medical billing job making the median salary when she graduates.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
