This is a stupid burden to put on people, nobody here knows the national budget well enough to make any sort of reasonable prediction about the actual numbers. Besides, you don't need mathematical notation to make a good argument.
The budget numbers are readily available and not at all hard to understand.
And yes, you do in fact need to discus what something might cost when making a good argument that the expense is worth it. When choosing what sort of home to live in I'm certainly you inquired about the cost. Unless you still live with your mother? You don't live in your parent's basement do you?
