a principal amount of $385 is placed in a savings account with an annual rate of 2.07% simple interest for 5 years. which formula would correctly determine the total account balance? a=(385)(0.207)(5)+385 a=(385)(0.0207)(5)+385 a=(385)(0.207)(5) a=(385)(0.0207)(5) question 8 (multiple - choice worth 5 points) (modeling functions mc) a cyclist is tracking weekly mileage while training for a race. the table models the number of miles, y, for a given week, x. x (weeks) 0 1 2 3 4 y (miles) 30 30 50.7 65.01 85.6683 which type of model would best fit the data, and why?
Answer
Explanation:
Step1: Recall simple - interest formula
The formula for simple interest is $I = Prt$, where $P$ is the principal amount, $r$ is the annual interest rate (in decimal form), and $t$ is the time in years. The total account balance $A$ is the sum of the principal $P$ and the interest $I$. So $A=P + Prt=P(1 + rt)$.
Step2: Identify values
Given $P = 385$, $r=2.07%=0.0207$, and $t = 5$.
Step3: Substitute values into formula
$A=385+385\times0.0207\times5=385(0.0207)(5)+385$.
Answer:
$A=(385)(0.0207)(5)+385$
