Write a function that represents the situation. find the balance a in the account after the given time period t. $6200 deposit that earns 8.4% annual interest compounded monthly; 18 months

Step-by-step explanation:

As this is the case of exponential growth, we can use the function

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,

The first answer is actually supposed to be A=6200(1.007)*12t
