Sharon spends 1248 because there are 52 weeks in a year and 24 * 52 = 1248
My first impulse is to say you don't provide enough info with which to solve this problem. We need to know how many inches in the model correspond to 1 foot in the actual plane (that is, the scale factor). What is the scale factor here?
Given that Teresa has a 5 out of 8 chance of making a profit, and an expected value of $1.50 in profit each turn, in the long run she has a better chance of making money than losing it.
Given that Teresa is playing a game of chance in which she tosses a dart into a rotating dartboard with 8 equal-sized slices numbered 1 through 8, and the dart lands on a numbered slice at random, and this game is this: Teresa tosses the dart once, and she wins $1 if the dart lands in slice 1, $3 if the dart lands in slice 2, $5 if the dart lands in slice 3, $8 if the dart lands in slice 4, and $10 if the dart lands in slice 5, but she loses $5 if the dart lands in slices 6, 7, or 8, to find the expected value of playing the game, and determine what can Teresa expect in the long run, after playing the game many times, she must perform the following calculation:
- (1 + 3 + 5 + 8 + 10 - 5 - 5 - 5) / 8 = X
- 12 / 8 = X
- 1.5 = X
Therefore, given that Teresa has a 5 out of 8 chance of making a profit, and an expected value of $1.50 in profit each turn, in the long run she has a better chance of making money than losing it.

There are 4! ways to sit the boys, and 4! ways to sit the girls.
Whether the boys sit to the left or the right of the girls don't matter, since it is a circular table AND rotations are not considered distinct arrangements.
So the total number of arrangements is the product of the two, namely n=4!4!. (note: (4!)^2 or (four factorial) squared.
