a customer will borrow $12,000 to buy a car. which loan option would allow the customer to pay the least amount of interest? f a 4 - year loan with a 5.2% annual simple interest rate g a 5 - year loan with a 4.2% annual simple interest rate h a 6 - year loan with a 4.7% annual simple interest rate j a 3 - year loan with an 8.4% annual simple interest rate
Answer
Explanation:
Step1: Recall simple - interest formula
The simple - interest formula 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. Here, $P=$12000$.
Step2: Calculate interest for option F
$r_F = 0.052$, $t_F = 4$. Then $I_F=P\times r_F\times t_F=12000\times0.052\times4 = 12000\times0.208=$2496$.
Step3: Calculate interest for option G
$r_G = 0.042$, $t_G = 5$. Then $I_G=P\times r_G\times t_G=12000\times0.042\times5 = 12000\times0.21=$2520$.
Step4: Calculate interest for option H
$r_H = 0.047$, $t_H = 6$. Then $I_H=P\times r_H\times t_H=12000\times0.047\times6 = 12000\times0.282=$3384$.
Step5: Calculate interest for option J
$r_J = 0.084$, $t_J = 3$. Then $I_J=P\times r_J\times t_J=12000\times0.084\times3 = 12000\times0.252=$3024$.
Answer:
F. A 4 - year loan with a 5.2% annual simple interest rate
