Step-by-step explanation:
Answer:
D. A(n) = P + (n-1)i*P
Step-by-step explanation:
The formula to calculate the simple interest is:

Replace i by
, then
SI = Pni
where n is the number of years.
So, for n-1 years, the simple interest is:
SI = P(n-1)*i
The Total amount is:
A(n) = P + (n-1)i*P
Answer:
x ≈ - 1.3
Step-by-step explanation:
16x + 20 = 0
16x + 20 - 20 = 0 - 20
16x = - 20
16x ÷ 16 = - 20 ÷ 16
x = - 1.25

- 1.25 rounds to - 1.3
