30 POINTS AND WILL GIVE BRAINLIEST
The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 41 minutes of calls is $19.26, and the remaining credit after 57 minutes of calls is $17.02. What is the remaining credit after 71 minutes of calls?

I really need help with the steps for this, thank you!!
