Answer:
The answer would be B, $1,680
Explanation:
So first of all you want to start by finding what P, r and t would be.
P = Principal amount ($$)
r = interest rate (%)
t = time
Once I found all of those I put them into the equation (l = Prt) and solved. That's how I came up with $1,680. Check the screenshot for my work :)
Have a great day!
