Answer:
<u>875</u> student tickets were sold.
Step-by-step explanation:
Given:
The drama club sold 2100 tickets to their last play.
Student tickets were $5 and adult tickets were $7.
They collected $12,950.
Now, to find the number of student tickets sold.
Let the number student tickets be
And the number adult tickets be
So, the total number of tickets:
Now, the total amount collected:
Putting the value of from above:
<em>Subtracting both sides by 14700 we get:</em>
<em>Dividing both sides by -2 we get:</em>
The number of student tickets = 875.
Therefore, 875 student tickets were sold.

Answer:
If you meant , then the answer is approximately 0.866.
If you meant , then the answer is approximately -2.909 which looks like what you meant based on the choices.
Step-by-step explanation:
First step is to get the exponential part by itself. The part that has the variable exponent which is the term.
To do this we need to subtract 4 on both sides:
Simplify:
The equivalent logarithmic form is:
I always say to myself the logarithm is the exponent that is how I know what to put opposite the side containing the log.
Anyways if you don't have options for computing in your calculator you need to use the change of base formula.
So
I don't see this as a choice so maybe you actually meant the following equation:
Let's see if this is the correct interpretation.
So the exponential part is already isolated.
So we just need to put in the equivalent logarithmic form:
Now we subtract 4 on both sides:
Again if you don't have the option for computing in your calculator, you will have to use the change of base formula:
