Kyle's fixed monthly salary in dollars $1800 and fixed percentage of his total sales for the month is 5%.

Fixed pay, also known as a fixed salary, is the predetermined and set sum that an employer pays to a worker at the conclusion of each payroll cycle. The term "fixed pay" refers to all compensation that the company guarantees, most frequently in the form of a monthly or annual salary.

We let his fixed monthly salary be x & his fixed percentage be y so our equations will be:

2,550 = x + 15,000y

3,050 = x + 25,000y

Subtract the equations

 3,050 = x + 25,000y

- 2,550 = x + 15,000y

500 = 10,000y

y = 10000/500

y = 0.05 or 5%

Potting the value of in first equation we get,

2,550 = x + 750

x = 2,550 - 750

x = $1800

Thus, Kyle's fixed monthly salary in dollars $1800 and fixed percentage of his total sales for the month is 5%.

Answer:

Step-by-step explanation:

Let x = amount charged for washing a car

     y = amount charged for vacuuming a car

38 = 5x + 4y (1)

28 = 4x + 2y (2)

Can be solved by substitution or simply subtracting the (1) and (2) equation.

By Substitution:

38 = 5x + 4y --->  solve for x

38 - 4y = 5x (transposed 4y to the other side of the equation and it's sign changes from (+) to (-).

[tex]\frac{38-4y}{5} =x[/tex]

substitute the value of x to the (2) equation.

28 = 4x + 2 y

[tex]28=4(\frac{38-4y}{5})+2y[/tex]

[tex]28=\frac{152-16y}{5} +2y[/tex] , then multiply both side by 5 to eliminate the denominator 5.

140 = 152 - 16y + 10y (transposed 152 to the other side, change sign from (+) to (-)).

140 - 152 = -16y + 10 y

-12 = -6y (divide both side by (-6)

y =  2 or $2 (amount charged for vacuuming)

Using any of the 2 equation, we can solve for the value of x.

38 = 5x + 4 (2) (we substitute, the value of y)

38 - 8 = 5x

30/5 = x

x= 6 or $6 (amount charged for washing)

The balance after 4 years if the interest is compounded continuously can be calculated using the formula for continuous compounding:

A = Pe^rt

where A is the balance after the period, P is the initial principal, r is the interest rate, and t is the time in years.

In this case, the initial principal is $12,000, the interest rate is 3%, and the time is 4 years.

A = 12000 * e^(0.03*4)

A = 12000 * e^0.12

A = 12000 * 1.128037

A = $13,529.96

∠ 3 = ∠ 4

since ∠ 3 = ∠ 4 and ∠ 4 = ∠ 1 with ∠ 2 = ∠ 1 = ∠ 4

By using the property of opposite angles of a parallelogram, we can say that ∠2 = ∠3.

Using the property that opposite angles of a parallelogram are equal,

In the parallelogram BEFG, ∠2 = ∠1 - equation 1

For a polygon with an interior angle sum of 2520, we have (n-2) * 180 = 2520. Solving for n, we get n = 14.
