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:
Sum of the sequence will be 648
Step-by-step explanation:
The given sequence is representing an arithmetic sequence.
Because every successive term of the sequence is having a common difference d = -3 - (-9) = -3 + 9 = 6
3 - (-3) = 3 + 3 = 6
Since last term of the sequence is 81
Therefore, by the explicit formula of an arithmetic sequence we can find the number of terms of this sequence
where a = first term of the sequence
d = common difference
n = number of terms
81 = -9 + 6(n - 1)
81 + 9 = 6(n - 1)
n - 1 =
n = 15 + 1 = 16
Now we know sum of an arithmetic sequence is represented by
Now we have to find the sum of the given sequence
= 8[-9 + 90]
= 8×81
= 648
Therefore, sum of the terms of the given sequence will be 648.
