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
Data on first test: 50, 50, 50, 50, 50
Mean = 250 / 5 = 50
In the next test, Data is: 50, 50, 50, 50, 100
Mean = sum of data / number of data
Mean = 50 + 50 + 50 + 50 + 100 / 5
M = 300 / 5
M = 60
In short, Your Answer would be 60
If You're looking for combined progress (average of class then, it would be: 50 + 60 /2 = 110/2 = 55
Hope this helps!
