Answer:
A = 180 customers.
Step-by-step explanation:
Let the number of customers that made additional purchases be A.
Given the following data;
Percentage = 72% = 72/100 = 0.72
Total number of customers = 250
To find the number of customers that made additional purchases;
A = 0.72 * 250
A = 180 customers.
Therefore, 180 customers made additional purchases on Wednesday.
Go to the third pic for your answer. I got problem 4 wrong but it shows the correct answer.
$92 - $20 = $72, because we shouldn't take allowance into account
3 + 6 = 9, because that is the total number of hours this person works per week
We should just do this:
72 / 9 = 8
This means that this person earns $8 per hour at his part time job.
Answer:

Step-by-step explanation:
Given:
To find:
- Summation notation of the given series
Summation Notation:

Where n is the number of terms and
is general term.
First, determine what kind of series it is, there are two main series that everyone should know:
A series that has common difference.
A series that has common ratio.
If you notice and keep subtracting the next term with previous term:
Two common difference, we can in fact say that the series is arithmetic one. Since we know the type of series, we have to find the number of terms.
Now that brings us to arithmetic sequence, we know that first term is 5 and last term is 251, we’ll be finding both general term and number of term using arithmetic sequence:
<u>Arithmetic Sequence</u>

Where
is the nth term,
is the first term and
is the common difference:
So for our general term:

And for number of terms, substitute
= 251 and solve for n:

Now we can convert the series to summation notation as given the formula above, substitute as we get:
