1/3 of the original number is X.
<span>Therefore, the original number is 3X </span>
<span>3X + X = 1348 </span>
<span>4X = 1348 </span>
<span>X = 1348/4 </span>
<span>3X = 3(1348/4)
x=1011</span>

Step-by-step explanation:
The answer is C. The 4th period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd period class.
Answer:
42 student tickets and 98 adult tickets
Step-by-step explanation:
Let's call the number of student tickets 's' and the number of adult tickets 'a'.
Then, we can write the two equations below:
5s + 8a = 994
a = 2s + 14
Using the value of 'a' from the second equation in the first one, we have:
5s + 8*(2s + 14) = 994
5s + 16s + 112 = 994
21s = 882
s = 42
Now, finding the value of 'a', we have:
a = 2*42 + 14 = 98
