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

Question

to represent this problem.

Answer 1

Let's denote the number of weekdays Lindsay practiced the guitar as \( x \).

According to the information given:

• She practices 50 minutes on Saturday.
• She practices 30 minutes on most weekdays, so for \( x \) weekdays, the total practice time on weekdays is \( 30x \) minutes.
• The total practice time she had last week is 140 minutes.

We can set up the equation based on this information:

\[ 30x + 50 = 140 \]

Now, to put this in the form \( px + q = r \):

• \( p = 30 \)
• \( q = 50 \)
• \( r = 140 \)

So the equation is:

\[ 30x + 50 = 140 \]
