Answer:
$210
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the annual interest rate as a decimal fraction, and t is the time in years.
Here, t = 7 years; p = $600; and r = 0.05.
Then the simple interest in this case is
i = $600(0.05)(7 yr) = $210
