<u>
</u>
<u>Solution:
</u>
<u>Absolutely Alice is wrong.
</u>
<u>
</u>
<u>As we know that the factors of any number are those numbers which can divide that number completely.
</u>
<u>
</u>
<u>so, factors of 8 are 1,2,4 and 8.
</u>
<u>Here one can see easily from all the four factors of 8 ,2,4,8 are even but 1 is odd.
</u>
<u>
</u>

Answer:
<em>y = 8</em>
Step-by-step explanation:
330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)
x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:
330x + 1220(17 - x) = 12730
330x + 20740 - 1220x = 12730
-890x + 20740 = 12730
-890x = -8010
x = 9
Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:
9 + y = 17
y = 8
Sarah bought y = 8 first class tickets.
