Answer:
Step-by-step explanation:
The equation for the amount of money in an account after a certain amount is deposited and compounded after t years once per year is

Our A(t) = 33800, P = 4400, r = .075 and we are looking for t. Filling in:
and

Begin by dividing both sides by 4400 to get

The only way to move that t our from its current position as an exponent is to take the natural log of both sides and follow the rules for natural logs:

The power rule of natural logs says we can move that exponent down in front, giving us:

Divide both sides by ln(1.075) to get

Do this division on your calculator to get
t = 28.2 years
Answer:
a. He read between 4 and 7 books.
b. x= 54/9
c. 6 books
Step-by-step explanation:
a. When I solved the equation, Finn read 6 six books which falls between 4 and 7 books.
b. You would divide 54 by 9 to find the number of books, he read. It would not make sense to multiply.
c. He read 6 books when we divide 54 by 9.
