2x + 8y=30

y=2

2x + 16 = 30

2x = 30 - 16

2x = 14

x = 14/2

x = 7

SALARY Sondra just started a job with an annual salary of $30,000. Each year, her salary will increase by 6%. If Sondra continues to work at this job, what will be her total earnings in the first 5 years, rounded to the nearest dollar?
A. 31,915
B. 40,147
C. 169,113
D. 179,260

Answers

Answer:

C

Step-by-step explanation:

1st year-> 30000

2nd year-> 31800

3rd year ->33708

4th year->35730.48

5th year -> 37874.3088

37874.3088+35730.48+33708+31800+30000= 169112.7888

                                                                             ≈ 169113

The solution is Option C.

The total amount of earnings of Sondra after 5 years is $ 169,113

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the annual salary of Sandra be A = $ 30,000

Now , the percentage increase in salary = 6 %

So , the equation will be

First year :

The increase in first year =  annual salary of Sandra + percentage increase in salary x annual salary of Sandra

The increase in first year = 30000 + ( 6/100 ) x 30000

                                         = 30000 + 1800

                                         = $ 31,800

Second year :

The increase in second year =  increase in first year + percentage increase in salary x increase in first year

The increase in second year = 31800 + ( 6/100 ) x 31800

                                         = 31800 + 1908

                                         = $ 33,708

Third year :

The increase in third year =  increase in second year + percentage increase in salary x increase in second year

The increase in third year = 33708 + ( 6/100 ) x 33708

                                         = 33708 + 2022.48

                                         = $ 35,730.48

Fourth year :

The increase in fourth year =  increase in third year + percentage increase in salary x increase in third year

The increase in fourth year = 35730.48 + ( 6/100 ) x 35730.48

                                         = 35730.48 + 2143.8288

                                         = $ 37,874.3088

Now , the equation is

The total earnings of Sondra is = First year salary + second year salary + third year salary + fourth year salary

The total earnings of Sondra is = 30000 + 31,800 + 33,708 + 35,730.48 + 37,874.3088

The total amount earnings of Sondra is = $ 169,112.7888

Therefore , the total amount earnings = $ 169,113

Hence , The total amount of earnings of Sondra after 5 years is $ 169,113

Determine if the expressions 100 divided by (25 divided by 5) and (100 divided by 25) divided by 5 are equivalent. If so, tell what property is applied. If not explain why.

Answers

Answer:

They aren't equivalent because when using P.E.M.D.A.S you solve what is in the parenthesis first. After you solve what is in the parenthesis the two expressions are completely different.  

Step-by-step explanation:

100/(5)=20    (4)/5= .8

The requried results of the two expressions are different (20 and 0.8), the expressions are not equivalent.

Expression 1:
100 ÷ (25 ÷ 5)

Evaluate the expression inside the parentheses.

25 ÷ 5 = 5

Replace the expression inside the parentheses with its result:

100 ÷ 5

Perform the division:

100 ÷ 5 = 20

So, the result of Expression 1 is 20.

Expression 2:
(100 ÷ 25) ÷ 5

Evaluate the expression inside the first set of parentheses.

100 ÷ 25 = 4

Replace the expression inside the first set of parentheses with its result:

4 ÷ 5

Perform the division:

4 ÷ 5 = 0.8

So, the result of Expression 2 is 0.8.

Since the results of the two expressions are different (20 and 0.8), the expressions are not equivalent.

The reason why they are not equivalent is due to the order of operations. In Expression 1, we first divide 25 by 5 and then divide 100 by the result, while in Expression 2, we first divide 100 by 25 and then divide the result by 5.
