Answer:
The answer is 96%
Step-by-step solution:
I just took the test and the way my test is set up, it doesn't show you the answer, you just have the ability to do it again and again with no limit. I saw that most people got all the other questions right but the salon one. And I did too before but after doing it over and over again I finally understood. So the question is Customer Retention = (# Customers at End of time Period less New Customers)/Customers at beginning of time Period
Multiply the result by 100 to convert to percentage
So pretty much what the question is saying is to subtract the numbers at End of time Period by the new costumers then divide that by the costumers at beginning of time Period then multiply the solution by 100 for the percentage. Most people probably dismissed the word less but it's indeed important and it would've been simpler if they just put a subtract sign but hey we got the answer anyway.
Answer:
(x+7)(x-2)
Step-by-step explanation:
Multiply the second fraction by (x-2) so that the value of it doesn't change
Let Bea = x
Therefore Andrew = x + 2
Chris = x - 3
Andrew * Chris = 66
(x + 2)(x - 3) = 66 Remove the brackets.
x^2 + 2x - 3x - 6 = 66
x^2 - x - 6 = 66 Subtract 66 from both sides.
x^2 - x - 72 = 0
(x - 9)(x + 8) = 0
Find the possible values of Bea's age
x - 9 = 0
x = 9 That value works. She can be plus 9 years old.
x + 8 = 0
x = - 8. There's no way she can be - 8 years old
So Bea is 9.
