We have 25% off coupon for a christmas tree already marked down to 10% if the original price of the tree is 189 how much will she pay

She will pay $122.85

Step-by-step explanation:

First, find the amount of the percents.

To do that, turn the percents into decimals.

25% --> 0.25

10% --> 0.10

Then, multiply each decimal with the original price.

189×0.25= 47.25

189×0.10= 18.90

Now that you have the amount of the percents, subtract both from the original price.

189- (47.25+18.90)

189-66.15= 122.85
