A car dealership pays you 5% commision on your first 10,00 car sales and 8% commission on the sale amount over 10,000. If you sold a 12,00 car, how much is your commission

You get 5% for 10,000.

You get 8% anything over 10,000.

You sold 12,000, which means you had 2,000 more than 10,000.

Calculate the commission on each amount with the appropriate rate:

10,000 * 0.05 = 500

2,000 * 0.08 = 160

Total pay: 500 + 160 = $660

Solve using substitution method 2x+2y=-3 2×-y=5

A) 2x + 2y = -3

B) 2x -y = 5

B) y = 2x -5

Substituting equation B into A

A) 2x +2*(2x-5) = -3

2x + 4x -10 = -3

6x = 7

x = 1.16666666

y = 2*1.16666667 -5

y = -2.66666666

B) 2x -y = 5

B) y = 2x -5

Substituting equation B into A

A) 2x +2*(2x-5) = -3

2x + 4x -10 = -3

6x = 7

x = 1.16666666

y = 2*1.16666667 -5

y = -2.66666666

PLEASE HELP!! if you don't know the answer don't comment!! If $945 is invested at an interest rate of 4% per year and is compounded continuously, how much will the investment be worth in 10 years?

Use the continuous compound interest formula A = Pert.

$947

$984

$1,028

$1,410

Answer:

Step-by-step explanation:

Looking at the formula, there are four variables which are P (principal or original amount), r (interest rate), t (time in the form of years), and A (final amount). e is not a variable because it represents a number just like represents a number, but e and are not the same in any respect.

Remember that you must convert the percentage into decimal form before inserting it into the equation. Your answer will be what you get after typing the equation above into the calculator. Remember to round based on what the multiple choice answers are rounded to.

8. If you were going to use the quadratic formula to solve the following equation and a = 9, what number would you use as the value for the variable 'b'? 3x + 8 = 9x2 The variable 'b' = ____. (4.0 Points) Part 9 - - 0/1 Answered Questions, 4.0 Points

Answer:

Remember, for solve the quadratic equation

we use the quadratic formula

We have the equation since a must be 9 then we pass the entire left side of the equation to the right side. We get the equation:

Then, observe that a=9 and b=-3
