Micah takes a job with a starting salary of $78,000 for the first year. He earns a 4% increase each year. How much does Micah make over seven years?

Answers

Answer 1
Answer:

Answer:

Micah make 616066.97 $ over seven years

Step-by-step explanation:

This increase is in the form of a geometric progression.

Micah takes a job with a starting salary of $78,000

First term of GP = $78,000

He earns a 4% increase each year

Common ratio =1+(4)/(100)=1.04

Sum of n terms of GP with first term a and common ratio r.

            s_n=(a(r^n-1))/(r-1)

How much does Micah make over seven years, so wee need to find sum of GP when n = 7.

        s_7=(78000(1.04^7-1))/(1.04-1)=616066.97\$

Micah make 616066.97 $ over seven years

           

Answer 2
Answer: So his job has a starting salary of $78,000 and he gets a 4% increase each year. 4% of 78,000 is 3120 since 3120 divided by .04 equals 78,000, and 78,000+3120 = 81120 x 7= 567,840. So every year he can make $81120 and multiply that by 7, Mica would earn $567,840 every 7 years with the 4% increase in his salary every year.

PLS HELP. The cost of printing a flyer to spread knowledge of an organization that you run is a flat rate of $9 plus $0.05 per copy. Let C represent the total cost of printing and x represent the number of copies. Write in symbolic form an equation that will relate C and x. Organize the data into a table of values. Begin with 500 copies, increase by increments of 500, and end with 2500 copies. How much would it cost to print 2500 flyers and what equation would you use?

Answers

The cost of printing a flyer to spread knowledge of an organization that you run is a flat rate of $9 plus $0.05 per copy. 

We are given the equation: 9.00+0.05x=C

500 copies:

Equation - 9.00+0.05(500)=C

1500 copies: 

Equation - 9.00=0.05(1500)=C 

2500 copies: 

Equation - 9.00=0.05(2500)=C 

C = 9 + 0.05x = 2500  flyers will cost $134
