Answer:
Using the simple interest formula
$3,629.34
Using the compound interest formula,
$3911.71
Step-by-step explanation:
Data provided in the question:
Total loan amount = $18,800
Interest rate = 4.29% = 0.0429
Time = 4.5 years
Now,
Using the simple interest formula
Interest = Principle × Rate × Time
or
Interest = $18,800 × 0.0429 × 4.5
= $3,629.34
Using the compound interest formula,
we have
Interest = Principle × (1 + rate )ⁿ - Principle
n is the time in years
= $18,800 × [tex](1 + 0.0429 )^{4.5}[/tex] - $18,800
= $22,711.71 - $18,800
= $3911.71
