9514 1404 393

Answer:

  marked price = Rs. 3900

Step-by-step explanation:

The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.

The marked price is Rs. 3900.

_____

<em>Check</em>

A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.

Samantha's notebook has 14 pages more than three times as much as Lisa's notebook.
MA_775_DIABLO [31]

Answer:

<h2>82</h2>

Step-by-step explanation:

L - number of pages of Lisa's notebook

3L + 14 - number of pages of Samantha's notebook

260 - number of pages of Samantha's notebook

The equation:

3L + 14 = 260          <em>subtract 14 from both sidesi</em>

3L + 14 - 14 = 260 - 14

3L = 246     <em>divide both sides by 3</em>

3L/3 = 246/3

L = 82

If f(x) = x and g(x) = 2, what is (f.g) (x)?
Mazyrski [523]

The value of (f.g) (x) is 2. Option B

<h3>What is a function?</h3>

A function can be defined as an expression or rule that explains the relationship between an independent and dependent variable.

Given the functions;

  • f(x) = x
  • g(x) = 2

To determine (f.g) (x), we need to know that it is a composite function

We substitute the value of g(x)  = 2 as x in f(x)

But we have f(x) = x

Then,

(f.g) (x) = 2

Thus, the value of (f.g) (x) is 2. Option B
