This is what i got...

For option 1 I think it's y=( .5(x-20))^2+20 for x>20

For option 2 I think it's y=30+.5*ln|x-25| for x>25

Question:

develop equations that model the two replacement pack options

(option 1) quedratic model, monthly access fee \$20, included gigabytes 20, cost per additional gigabyte *see below (*)

(option 2) logarithmic model, monthly access fee \$30, included gigabytes 25, cost per additional gigabyte *see below (**)

(*) The charge option 1 will increase quadratically after 20 gigabytes with customers paying \$0.50.

(**) The charge option 2 will increase logarithmically in the form ƒ(x) = a + b 1n|x| after 25 gigabytes with customers paying \$0.50.
