The correct answer is:
It is helpful to round to the hundredths when we are dealing with money.
Explanation:
Our monetary system has dollars and cents, and it takes 100 cents to make a dollar. This means we would have a measurement to the hundredth place for money. If we are dividing and get a quotient that goes past the hundredths place, if it is money, we should round it to the hundredths place.
2 : 5
1 : 4
3 : 5
I know it would be nonlinear because neither Variable X OR Y have a constant rate of change.
Unfortunately, I don't know whether it is positive or negative.
