<h3 /><h3>Compound interest Computation</h3>
Given Data
A = P + I where
P (principal) = $2,000.00
I (interest) = $431.01
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 2,000.00(1 + 0.05/1)(1)(4)
A = 2,000.00(1 + 0.05)(4)
A = $2,431.01
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 5% per year compounded 1 times per year over 4 years is $2,431.01.

Answer:
number 2 is 240
Step-by-step explanation:
120 is for 4 but if you double it because its 8 its 240
If the amount of time is x seconds, then 15*x is the amount ran by one child and 6*x is the amount ran for the other child due to that they add 15 or 6 feet for each second. In addition, since they are 450 feet apart, 15x+6x=450=21x. Dividing both sides by 21, we get x=around 21.4 seconds. Since the mother is always between them, when those two meet is when the three meet. Therefore, she runs 20* around 21.4= around 428.57 feet
