4y+yz is the correct answer

Answer:

4y + yz

Step-by-step explanation:

the grouping symbols can be parentheses, brackets, or in this case a sign of multiplication ·

you have the expression

y · 4 +y ·z

to eliminate the symbol  · from the first term you just do the multiplications:

y multiplied by 4 is equal to 4y

and to eliminate the symbol  · from the second term, since we don't know the values to y and z, we let them indicates as yz, because the simple fact of two variables written together is indication of a multiplication.

So the result is:

4y + yz

Jenny owns a salon. She had 150 customers at the end of the third quarter, 151
Alika [10]

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.
