Expense by AIR- Let Crystal have 100$ for Air travel.
Then, for Plane-40$; Meals and Lodging-50$; Miscellaneous-10$.
Expense by CAR
Travel = 10% less than Plane, i.e, 36$.
Miscellaneous-10$ (Remains same)
Meals and lodging are 54$.

Percentage increase = \(\frac{54-50}{50}*100\) = 8%.

B is the answer.

The percentage breakdown of a budget is given for transportation, meals and lodging, and miscellaneous expenses.

If transportation costs 10% less, more can be spent on meals and lodging while keeping total expenses the same.
Since no amounts of money are given and the answer choices are percents, we pick $100 for the total budget.

If the total budget is $100, then the amount allocated to airfare would be
0.40 × $100 = $40,
and the amount for meals and lodging would be
0.50 × $100 = $50.
A 10% reduction in the first amount would be
0.10 × $40 = $4.
Reallocating that part of the budget to meals and lodging would allow for $50 + $4 = $54 to be spent on that category.
An increase of $4 from an original amount of $50 is
4/5×100% = 8%
So correct answer is B

Let total expense=100
then plane=40,meals+lodging=50 and misc=10

Now, 10% less than flying =36
misc. is same i.e. 10
==>meals+lodging=100-36-10=54

which is 4 more than previous 50, which is an 8% increase

Ans:B
