Write a function rule to describe the the amount of change c(x) you get from a $20.00 bill if you buy x pounds of candy at $2.25

a pound.
c(x) = 20x + 2.25

c(x) = 20x - 2.25

c(x) = 20 - 2.25x

c(x) = 20 + 2.25x

The correct answer would be c because I buy x pounds of candy for 2.25, and I use a 20 dollar bill to pay, so 20-2.25x. Would be the change i get back.
