P [ (1+r)^n -1 ] / r
where P is the annual payment = 95*12 = 1140
r = 0.03
1+r = 1.03
n = 10
so (1+r)^10 = 1.344
-1 = 0.344
so
1140 [ 0.334] / .03 = 13068.82
approximately. I may have carried more or less significant figures

Poorly worded question.

To use the formula:
amount = paym( (1+i)^n - 1)/i
the payment period and the interest period MUST be the same
i.e. if the payments are made monthly, then the interest rate must be
compounded monthly
In our question it says that the account earns 3% annual interest. Unless otherwise
stated that implies compounded annually.

to get one of their answers ....
i = .03/12 = .0025
n = 10*12= 120
amount = 95( 1.0025^120 - 1)/.0025 = 13,275.43 <----- one of their answers

correct solution:
We must convert the 3% annual rate to a rate compounded monthly
We have to find the monthly rate i so that
(1+i)^12 = 1.03
1+i = 1.03(1/12) = 1.00246627
So the equivalent monthly rate to an annual rate of 3% is .00246627..
and could be stated as 12(.00246627..) or 2.9595..% per annum, compounded monthly

amount = 95 (1.00246627)^120 - 1)/.00246627 = 13,247.56 , different from theirs by about $28

check:
to show my rate is correct, lets just see what $100 would grow to at
both rates in 1 year:
at 3% per annum: 100(1.03) = $103.00
at 2.95595% per annum compounded monthly = 100(1 + .0295595../12)^12 = $ 103.00
