Answer:
$108
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.
[tex]I=Prt\\[/tex]
I = interest amount
P = principal amount
r = interest rate (decimal form)
t = time
First, change 2% into its decimal form:
2% -> [tex]\frac{2}{100}[/tex] -> 0.02
Next, plug in the values into the equation:
[tex]I=1,800(.02)(3)[/tex]
[tex]I=108[/tex]
