Answer:
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
