So, first let's solve for the total amount that Alvina contributed to her 401k account, by multiplying the amount contributed per month ($85) times the number of months (12):

So, Alvina contributed $1020 to her 401k account.
Her employer contributed 20% of that, which we can find by multiplying the amount Alvina contributed by .2:

So we know that Alvina's employer contributed $204 to her 401k account.
We can add these two numbers to get the total:

And that's our final answer of $1224 total contributed to the account!
Hope I helped, and let me know if you have any questions! :)
