Answer:
The narrative in the question can not be described as a function
Step-by-step explanation:
For the purpose of clarity, we will rephrase the question. The key point in the question is to determine if the price and the model are related and if they fit into independent and dependent function.
Moving forward, to properly answer this question, it will be good for us to understand what dependent and independent functions are.
DEPENDENT FUNCTIONS: These are functions or can also be refereed to as variable that represents quantities or values whose parameter depends on how the independent variable is manipulated.
Example:
You are doing job to earn your a salary. For each project you do, you earn $10 dollar. In this case, the dependent variable is the amount of money you earn because the amount of money you earn depends on how many job or project you do.
INDEPENDENT FUNCTIONS: These are functions or can also be refereed to as variable that we have control over in the process of an event therefore, we are at liberty to manipulate it as we so wish as indicated in the dependent variable.
Going back to the narrative of the question, the narrative in the question can not be described as a function because the two identifies variables which are the price and the model years are been altered due to the fact that it is a used car lot so they have both lost their true value or worth. However, some might argue that price here is the independent function or variable while model year is the dependent variable.
Answer:
she need to pay is $550.40
Step-by-step explanation:
given data
interest = 4.2 % compounded quarterly = 0.042 / 4 = 0.0105
future value = $7000
time = 3 year = 3 × 4 = 12 months
to find out
How much money she need to pay
solution
we will apply here formula for future value for compound quarterly
that is
future value = principal × 
.............1
put here all these value
future value = principal ×
7000 = principal × 
principal = 550.40
so she need to pay is $550.40
Yes, yes it is!
Because every point on the line of this equation is also a solution!
THis is called a linear equation!
