BaLLatris [955]

Answer:

The principal for the account is $375.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

The interest earned after 1 year is $12 .If the interest rate is 3.2% for account (A).

This means, respectively, that t = 1, E = 12, I = 0.032

We want to find P.

E = P*I*t

12 = P*0.032*1

P = \frac{12}{0.032}

P = 375

The principal for the account is $375.
