Answer:
B
Step-by-step explanation:
The definition of a function is that any input will only have one output. Here, the input is the number of years, and the output is the value of the car. We know this because the question is asking why the value of the car is a function of the number of years. Therefore, based on the number of years, the value of the car is given.
Going back to the definition of a function, we can apply this year to say that any number of years will only have one car value. Another way to say this is that each time is associated with exactly one car value.
Answer: E. 40
Step-by-step explanation:
<u>Concept: </u>
- When you encounter questions that state "what percent of [a] is [b]" then it means asking for a fraction of b to a, which is "(b/a)×100%".
- If you are still confused, I would provide some examples
- What percent of 20 is 5: (5/20)×100% = 25%
- What percent of 10 is 2: (2/10)×100% = 20%
---------------------------------------------------------------------------
<u>Solve:</u>
(16/40)×100% = 0.4 × 100% = 40%
Hope this helps!! :)
