Which of these is mostly likely to describe the change received from a cash purchase?

A. Whole Number

B. Negative Integer

C. Rational Number

D. Irrational Number

It would be a rational number, c because if you are getting cents back, you are getting a decimal, which isn't a multiple of 1 so it can't be a whole number or negative number, and it can't be irrational because all cents are less than 100 which means they all terminate so they are rational.
