I have been struggling on this problem!! -> Jada and Zeke compare their monthly text message plans. Jada's plan costs $5 plus an additional $0.05 per text. Zeke's plan costs $0.10 per text.

The equations below show the cost c, for each plan depending on how many texts, t, are sent.
Jada's Plan: c=0.0St+5 Zeke's Plan: c-0.10

Enter the number of text messages they each sent​
update: ai solved for it me
