Hello!
Lynne invested 35,000 into an account earning 4% annual interest compounded quarterly she makes no other deposits into the account and does not withdraw any money. What is the balance of Lynne's account in 5years
Data:
P = 35000
r = 4% = 0,04
n = 4
t = 5
P' = ?
I = ?
We have the following compound interest formula
So the new principal P' after 5 years is approximately $42,706.66.
Subtracting the original principal from this amount gives the amount of interest received:

Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then
...(i)
where, k is the constant of proportionality.
From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).
Putting x=2 and y=1 in (i), we get
Putting , we get
Therefore, the correct option is A.
