How much did Donna get 25% off? ** Donna got $200 x 25/100 = $<<200*25/100=50>>50 less for the porcelain vase.
How much did Donna pay for the porcelain vase? ** So, the porcelain vase is now $200 - $50 = $<<200-50=150>>150.
How much did Donna pay in sales tax? ** Donna has to pay $150 x 10/100 = $<<150*10/100=15>>15 for the sales tax.
How much did Donna pay in total? ** Therefore, she paid $150 + $15 = $<<150+15=165>>165 in total.
