Solve the equation for the indicated variable.
Answer:
Option A
Step-by-step explanation:
[tex]D=3ef^2\\[/tex]
we need to make e the subject of the formula so here goes,
On the right side 3 is being multiplied by ef^2 so when it moves to the left side it will divide
[tex]\frac{D}{3}=ef^2[/tex]
now f^2 is also being multiplied by e on the right side so when it moves to the left side it will divide
[tex]\frac{D}{3f^2}=e\\\\[/tex]

An audio books club charges an initial joining fee of $20.00. The cost per audio book is $15.00. The graph shows the cost of belonging to the club as a function of audio books purchased. How will the graph change if the cost per audio book goes up by $1.00?
(The new function is shown by the dotted line.)
Answer:
The graph will change by simply having an increased slope of 16 instead of 15.
Step-by-step explanation:
For this problem, we will consider the initial case as stated by the problem where the joining fee is $20 and each book is $15. Let x represent the number of books that we have purchased. Then, we can write the following function to represent the cost of this club.
f(x) = 15x + 20
Note, if x = 0, meaning we have no books, then
f(0) = 15(0) + 20
f(0) = 0 + 20
f(0) = 20
Which is the cost of our joining fee. If x = 1, meaning we have 1 book, then
f(1) = 15(1) + 20
f(1) = 15 + 20
f(1) = 35
Which is the cost of our joining fee and 1 book, which matches our graphed function.
Now, let's consider that the cost of the book is $16 instead of $15 ("the cost per audio book goes up by $1.00"). Then we can modify the slope of our function to reflect this change giving us the new function:
g(x) = 16x + 20
In this new function, our slope increased from 15 to 16, to account for the increase in cost, but our initial 20 remained the same.
So the graph will change by simply having an increased slope of 16 instead of 15.
Cheers.
Answer:
The new function will have a steeper slope, so...
Step-by-step explanation:
Le: t x ----> the number of audio books purchased
y ---->the cost of belonging to the club in dollars
case 1 (Originally) :
y = 15x + 20
case 2 ( the cost per audio book goes up by $1.00) :
y= (15+1)x+ 20
y = 16x + 20
The slope of the new function is greater than the slope of the original function
The new function will have a steeper slope:
16 $/ audio book > 15 $/audio book

In your own words, what do the terms sales tax and discount mean? Is a 5 percent sales tax a percent of increase or decrease? What about a 15 percent discount?
lol help-
Answer:
Sales tax is an increase in the price of the item while a discount is the decrease of the price. A 5% sales tax is an increase since your paying an extra 5% of the item price. 15% discount is a decrease since your now only paying 85% of the original price. Hope that helps
Answer: In layman's terms, that means if the original price of something you sell was $100, but you offer a 50% discount, then the taxable price is $50. Sale Price = original price – (% of discount * original price)
Sales Tax = Sales Tax rate * Sale Price.
Sales Tax = 0.05 * $17.21 = $0.8605 = $0.86. How do I add 5% to a number?
Divide the number you wish to add 5% to by 100.
Multiply this new number by 5.
Add the product of the multiplication to your original number.

help. PLEASE.
Answer:8.5
Step-by-step explanation:
Answer:
step one
find the difference between marked price and the selling price, which is 24-15.50=8.5
step two apply the formula which is, difference divided by marked or original price and then multiple by 100
eg (8.5÷24) × 100= 35.4
so now round off to the nearest percent that's 35%
Before a renovation a movie theater had 117 seats after the renovation theater had 173 what is the approximate percentage increase of the number of seats in the theater if necessary round to the nearest 10th in percentage
Answer:
47.86%
Step-by-step explanation:
Total number of seats in a movie theater Before a renovation = 117
Total number of seats in a movie theater after a renovation = 173
We need to find the percentage increase of the number of seats. It can be calcualted as :
[tex]\%=\dfrac{\text{|final number-initial number|}}{\text{initial number}}\times 100\\\\=\dfrac{173-117}{117}\times 100\\\\=47.86\%[/tex]
So, the increase in percentage is 47.86%.
