In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.

Answer:
The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
Step-by-step explanation:
Given the sequence
9, 17, 25, 33
a₁ = 9
<em>Determining the common difference</em>
d = 17-9 = 8
d = 25-17 = 8
d = 33-25 = 8
As the common difference between the adjacent terms is same and equal to
d = 8
Therefore, the given sequence is an Arithmetic sequence.
An arithmetic sequence has a constant difference 'd' and is defined by

substituting a₁ = 9, d = 8 in the equation


Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
Answer:

Step-by-step explanation:
Given that,
A sequence 352,345,338.
First term = 352
Common difference = 345-352 = -7
We need to find the 37th term of the sequence.
The nth term of an AP is given by :

So, the 37th term of the sequence is 100.
Answer:
Chris earned $ 43,344 each year
Monthly Chris earns $ 3,612
Step-by-step explanation:
If you earn a fixed amount of money each month, for 2 years and one year you have 12 months, then 2 years equals 24 months.
To know how much you earn each month we divide the total amount earned in the two years between 24 months
I = $ 86,688 / 24
I = $ 3,612
Monthly Chris earns $ 3,612
To calculate what he earned each year we divided $ 86,688 / 2
I = $ 86,688 / 2
I = $ 43,344
Chris earned $ 43,344 each year
