Answer: A, C, and E
Step-by-step explanation:
Hi, to answer this question we have to analyze the function given:
C(b) = 2.75b + 10
Where:
- Independent variable: b (number of books)
- Input = b
- Output = C = annual cost
- Dependent variable = C (depends on b, the independent variable)
So:
A. The number of books purchased is the independent variable. TRUE
B. The input is the yearly cost. (FALSE, the input is the number of books )
C. The total yearly cost depends on the number of books purchased. TRUE
D. The number of books purchased is determined by the yearly cost. FALSE , the yearly cost is determined by the number

Answer:
271,403 is rounded to 270,000 because the 1403 before it is less than 5000, 4 and below drop it down, 5 or more bump it up.
Step-by-step explanation:
Just do each number to they square root
The number of miles for which the car has been driven if one paid $122.50 as in the task content is; 2.5 miles.
<h3>For how many miles was the car driven?</h3>
It follows from the task content that the total amount paid was; $122.50.
Hence, after subtraction the constant charges, for the day and for gas, the remainder is;
$122.50 - $50 - $35
= $37.50.
Ultimately, if the charge per mile is $15, then the number of miles driven is; $37.50/$15
= 2.5 miles.
