Davis must practice kicking a football 160 minutes each week. He kicks the ball 40 minutes each day. Write a function to represent the number of minutes Dalton has to practice after \( x \) days.

To represent the number of minutes Dalton has to practice after \( x \) days, we can create a simple linear function. Since Davis practices for 40 minutes each day, the function can be expressed as: \[ P(x) = 160 - 40x \] In this equation, \( P(x) \) represents the remaining minutes Davis has left to practice after \( x \) days. For instance, after 2 days of practice, we can substitute \( x \) with 2: \[ P(2) = 160 - 40(2) = 160 - 80 = 80 \] So, he would have 80 minutes left to reach his weekly goal of 160 minutes! Now, if he practices every single day, even on weekends, he'll get to reach his goal in just 4 days! Isn't that a fun little math challenge?
