Meals are only 11% for the vacation budget. This means that meals would go over 100% like this:
You also know that you have $550 for meal (your part) but you want to know what your total vacation budget is(your whole) (x), so you would set it up like this
Now you sent them equal to solve for x:
cross multiply:
11x = 55,000
x = 5,000
This means that your total vacation budget is $5,000
