A.5e+n=$68
e+2n=$55
Because li bought 5 earrings which represents 5e and the n represents 1 necklace and jen bought 1 pair of earrings which represent e which means 1 and the 2n represents 2 necklaces which totals $55 like said in the problem
Let the number of adults equal x, and the number of children equal 5x.
26(5x) + 69x = 94908
194x = 94908
x = approx. 489
About 489 adults bought tickets.
We are told that every 9th person gets free popcorn and every 6th person gets free apple juice at the movie theater. We want to show if the 36th person is the first to get both free popcorn and apple juice.
Since every 9th gets free popcorn, then the 9th and 18th and 27th and 36th people get it. We can use numbers and show this as multiples of 9.
9, 18, 27, 36, 45, 54, ...
And we repeat it for every 6th and the free juice.
6, 12, 18, 24, 30, 36,....
Shani thinks 36 comes first, and she's wrong. 18 appears on the list before 36 as something that's common. What are we finding is the lowest common muliple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
The lowest common multiple will have a 2, a 3, and a second 3 (because we don't double count). 2 x 3 x 3 = 18. This matches up to the list of multiples.
Thus, Shani is wrong that the 36th person gets both free items, as she did not account for the 18th person gettting both free items
