Note: you may need to leave off the dollar sign and leave off the comma if you are typing the answer into a computer system.

Explanation:

We'll use the compound interest formula

A = P*(1+r/n)^(n*t)

The variables are:

In this case, we know the following values:

They are all plugged into the formula mentioned to get

A = P*(1+r/n)^(n*t)

A = 9500*(1+0.045/12)^(12*4)

A = 11369.7365854849

A = 11,369.74

After 4 years, there will be $11,369.74 in the account.

Side note: The info that "assume 360 days in a year" would only apply if we were compounding daily.
