Johan practices the drums for 45 minutes on Saturday and 25 minutes on most weekdays. Last week he practiced 120 minutes. How many weekdays did he practice? Write an equation in the form of px + q = r to represent this problem.(3 points)

1 answer

Let x be the number of weekdays Johan practiced.
Each weekday Johan practiced 25 minutes so he practiced 25x minutes.
Last week he practiced 120 minutes, so his total practice time was 120 = 25x + 45.
Thus, the equation is 25x + 45 = 120. Answer: \boxed{25x + 45 = 120}.
