Max has been offered positions by two car companies. The first company pays a salary of $7,500 pluscommission of $1000 for each car sold. The second company pays a salary of $17,500 plus a commission of
$500 per car sold. How many cars would need to be sold to make the total pay the same?

Answers

The number of cars would need to be sold to make the total pay the same is 20.

Given that, the first company pays a salary of $7,500 plus commission of $1000 for each car sold.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of cars be x.

The first company pays = 7500+1000x

The second company pays = 17500+500x

So, 7500+1000x=17500+500x

⇒ 1000x-500x=17500-7500

⇒ 500x=10000

⇒ x=10000/500

⇒ x=20

Therefore, the number of cars would need to be sold to make the total pay the same is 20.

Tanya has 44 quarters and dimes worth$8.30. how many of each type of coin does she have

Answers

Tanya has 26 quarters and 18 dimes.

Given that Tanya has 44 quarters and dimes which worth $8.30, we need to find the number of each coin type,

To find the same we will use the concept of system of Linear equations,

Let's solve this problem step by step.

Let's assume Tanya has x quarters and y dimes.

The value of x quarters is 25x cents.

The value of y dimes is 10y cents.

According to the given information, the total value of the quarters and dimes is $8.30, which is equivalent to 830 cents. So we have the equation:

25x + 10y = 830 ...........(Equation 1)

Tanya has 44 coins in total:

x + y = 44 ...........(Equation 2)

Now, we can solve this system of equations (Equation 1 and Equation 2) to find the values of x and y.

Multiplying Equation 2 by 25, we get:

25x + 25y = 1100 ...........(Equation 3)

Subtracting Equation 3 from Equation 1, we eliminate the x term:

25x + 10y - (25x + 25y) = 830 - 1100

-15y = -270

Dividing both sides by -15, we get:

y = (-270)/(-15) = 18

Substituting the value of y back into Equation 2, we can find x:

x + 18 = 44

x = 44 - 18 = 26

Therefore, Tanya has 26 quarters and 18 dimes.

Suppose Tanya has d dimes worth 10d cents and (44-d) quarters worth 25(44-d)
cents. Now total value = 830 cents, ie., 10d + 25(44-d) = 830, ie., 1100 -830 = 15d, ie., d = 54/3 = 18. Therefore A has 18 dimes and 26 quarters.

Find the inverse of the function f(x) = 2x - 4.g(x) = 1/2x - 1/4
g(x) = 1/4x - 1/2
g(x) = 4x + 2
g(x) = 3x+2

Answers

Answer:

D, g(x) = 1/2 x + 2

Step-by-step explanation:

The second answer IS ONE TO ONE

Answer:

None of the options are correct, but I got g(x)=1/2x+2.

Step-by-step explanation:

You start with the equation. You first need to change f(x) to y, and switch the x and y values. After this, your equation would be x=2y-4. Then, you need to icolate the y value, and to do that you first cancel out the four by adding it to both sides, and now your equation should be x+4=2y. The second step in icolating the y value is dividing everything in the equation by two. Now that the y is icolated, you equation should be y=1/2x+2. You then change the y to be g(x), and that's how I got my answer, g(x)=1/2x+2. You should ask your teacher about this, becuase from my calculations, none of the given responses would be correct. Sorry if that doesn't help you at all but yeah

Catherine's employer matches 25% of her 401(k) contributions — up to $2000. Catherine's salary is $50,000, and last year she contributed $10,000 to her 401(k) plan. What was her employer's contribution to the 401(k)?

Answers

We have been given that Catherine's employer matches 25% of her 401(k) contributions or a maximum of $2000. Further we are given that Catherine's salary is $50,000 and she contributed $10,000 to her 401(k) plan.

Let the contribution form her employer be $x. We are given that her employer matches 25% of Catherine's contribution under 401(k) plan. Therefore, contribution made by employer would be either 25% of 10,000 or 2000, whichever is lesser.

Let us find 25% of 10,000.

25\% \text{ of 10000 } = 10,000 * (25)/(100) = \$2500

Since 25% of 10,000 is more than 2000, therefore, Catherine's employer would make a contribution of $2000.

25% of $10,000 is $2,500

But because they only match "up to $2,000," her employers contribution was $2,000
