Answer:
Given: Principal(P) = $ 5000 , T = 3.5 years and R = 5%.
Using the formula of Simple Interest (I) given by;
.......[1] , where P is the Principal amount of money to be invested, R be the rate of interest and T be the time.
Substitute the given values of P , R and T in [1] we have;


Simplify:

An Ending balance is calculated by subtracting cash outflows, interest paid for financing and principal paid on financing.
Ending Balance = $ 5000 + $ 175 = $ 5,175.
Therefore, the ending balance is $ 5,175
1) 2x-1 or x=1/2
2) 5a-16 or a=16/5
Think about this as a table of values where domain is the x values and range is the y values.
f(4) wants the y-value when the x-value is 4
f(4) = 1/2
The second question wants us to find the x-value when f(x) also known as the y-value is 4.
f(x) = 4
x = 8
answers: 1/2, 8
