Let's denote the number of weekdays that Lindsay practiced as x.
Therefore, the total time she practiced on weekdays would be 30x minutes.
On Saturday, she practiced 50 minutes.
So, the total time she practiced in a week would be 30x + 50 minutes.
According to the problem, she practiced a total of 140 minutes last week.
Therefore, we can write the equation as 30x + 50 = 140.
Lindsay practices the guitar 50 minutes on Saturday and 30 minutes on most weekdays. Last week she
practiced 140 minutes. How many weekdays did she practice? Write an equation in the form px + 9 = r to
represent this problem.
