Answer:
You would have $343.37 at the end of the 2 years.
Step-by-step explanation:
Interest earned is like bonus money the bank pays you just for keeping money

P: the starting balance of the account (also called initial deposit, or principal)
A: the new balance in the account after N years.
t: the number of years or time
r: the interest rate, (in decimal form)
n: the number of times the interest is compounded each year.
Annually = each year = 1
P =$300, r = 7%, t = 2, n = 1, A = ?
Substitute the numbers into the "Compound Interest Formula".











So you would have $343.37 at the end of the 2 years.
Look at the chart

Answer:
You input the equation they give you into the table to get an outcome. The Equation they gave you is x=y. simply, what ever X is, thats what y is. x=y. On the table it says that X is 3. If x is 3 then y is three because they are equal. if X is 7 then Y is 7. its the same throughout the whole table. To write it as an ordered pair you write (X,Y) if x is three y is three so the ordered pair would look like (3,3)
So the question is asking to covert the said formula by making the a as the solution or the ask of the said equation, well in that matter, I would say, base on my own conversion and further computation about the said equation, the value of a is (y+z)/(x+w). I hope this would help
