The function, f(x)=70n-400, models the profit of the instructor of a guitar class per month, where n is the number of students e
zimovet [89]

profit=f(x)

so solve for f(x)=1000

1000=70n-400

add 400 to both sides

1400=70n

divide both sides by 70

20=n

20 students need to be enrolled to make a profit of 1000.00

Which of the statements are true about the function f given by f(x) = 100-e? Select all that apply.
tatiyna

From the above function, it is clear that the value of f is never 0. Hence the statement that is true is (Option E), See explanation of same below.

<h3>What is the explanation for the above function?</h3>

Note that the function is related to Euler's number which is depicted as:
e ≈ 2.7182. The function is given as:

f(x) = 100 * e^{-x}

Assuming x = -2, we'd have:

100 * 2.7182^{-2}

= 271.82^{-2}

= 0.00001353354

Hence, even when x tends < 0 the function f(x) thus, is never 0. See the attached graph for confirmation.

A car dealership paid $9,000 for a car. The sticker price is $10,395 for a customer to buy the car. a. What’s the markup in doll
Sladkaya [172]

Answer:

1) To determine how much the change of $9,000 to $10,395, we must subtract 9,000 from 10,395;

10,395 - 9,000 = $1,395 is the change in <u>price</u> (an increase).

Formula to find percentage of change;

Change in price/original amount x 100% (100/100)

Replace those values:

1,935 (change in price/increase)       100

_____                      x                        _____ =<u> </u><u>%0.215</u>

9,000(original amount)                      100
