Here A is function of t, where A gives the balance after time t.
P = initial deposit,
r = rate of change or rate of interest,
$6200 deposit that earns 8.4% annual interest compounded monthly for 18 months.
So,
P = $6200,
r = 8.4% annual =
monthly =
monthly (as interest compounded monthly)
t = 18 months,
Putting all the values,
