math 9 help

A house is being renovated for $50,000. Right now the HST is 12% and is charged on all renovations. After April the HST will be gone and be replaced with PST of 7% and the GST of 6%. Renovations will only have to charge GST. How much money will the homeowner save if they wait until April to get the renovations done?
