Answer:
$621.08
Step-by-step explanation:
The formula for the amount (A) resulting from principal P being invested at rate r continuously compounded for period t is ...
A = Pe^(rt)
Filling in the given numbers and doing the arithmetic, we get ...
A = $400e^(0.055·8) ≈ $621.08
9w - 7 = 5
9w= 5+7
9w=12
w= 4/3 or 1.33
