To determine the total amount Margery expects to spend on her vacation considering the hotel expenses and applying a 10% discount, we first need to establish her original hotel cost before any discounts.

Assuming her original hotel expense before the discount is X, a 10% discount reduces that cost by \(0.10X\). Therefore, the price Margery pays after the discount becomes \(X - 0.10X = 0.90X\).

If we know the other expenses associated with her vacation, we can simply add them to the discounted hotel cost to find the total expected to spend.

For scenario C, the total amount of $1381.40 likely reflects the correct calculation of combining her discounted hotel expense and other vacation costs. This means that after calculating the discount and adding the additional expenses, the total fits the provided amount.

Hence, to verify that $1381.40 is correct, we can backtrack by considering a total expense scenario where the hotel discount correctly adjusts her overall expenses with the required calculations, confirming this amount through addition and percentage deduction practice.

This methodical approach is crucial when working through vacation expenses, as it ensures accurate budgeting and understanding of any discounts applied to larger costs.
