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 + q = r to represent this problem.
(2 points)
__x + __ = __
Let's represent the number of weekdays Lindsay practiced with the variable x.
Since she practiced for 50 minutes on Saturday, we need to account for that day as well.
Therefore, the total time she practiced on weekdays is 30x.
We can now set up the equation:
30x + 50 = 140
