Answer:
(20 + n)¢
Step-by-step explanation:
With Company X, it costs 35¢ to connect and then 5¢ for each minute.
So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢
Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.
So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.
Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)

<u>Step-by-step explanation:</u>
Let's work on the product given.
- => 4/5 x 11/9
- => 4 x 11/9 x 5
- => 44/45
Now, let's verify all options.
<u>- Option A -</u>
- Statement: Because 11/9 is greater than 1, the product of 4/5 and 11/9 is less than 4/5.
- Correct/Incorrect: The statement is incorrect.
- Reason: The statement is incorrect because the result we got from the product is greater than 4/5 while the statement states that the result should be less than 4/5. Hence, this is incorrect.
<u>- Option B -</u>
- Statement: Because 11/9 is less than 1, the product of 4/5 and 11/9 is greater than 4/5.
- Correct/Incorrect: The statement is incorrect.
- Reason: The statement is incorrect because 11/9 is not less than 1.
<u>- Option C -</u>
- Statement: Because 11/9 is less than 1, the product of 4/5 and 11/9 is less than 4/5.
- Correct/Incorrect: The statement is incorrect.
- Reason: The statement is incorrect because 11/9 is not less than 1.
<u>- Option D -</u>
- Statement: Because 11/9 is greater than 1, the product of 4/5 and 11/9 is greater than 4/5.
- Correct/Incorrect: The statement is correct.
- Reason: This is because 11/9 is greater than 1 and the product is greater than 4/5. Hence, this statement is correct.
<u>Conclusion:</u>
We can now conclude that statement D is correct.
