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

To create an equation that represents Lindsay's guitar practice, we can break down the information given:

• Let \( x \) be the number of weekdays Lindsay practiced.
• On Saturdays, she practiced 50 minutes.
• On most weekdays, she practiced 30 minutes each.

From the information provided, the total amount of time Lindsay practiced last week is the Saturday practice plus the weekday practices.

We can express the total practice time as follows:

• Practice on Saturday: 50 minutes
• Practice on weekdays: \( 30x \) minutes (where \( x \) is the number of weekdays)

The total practice time equation can then be written as:

\[ 30x + 50 = 140 \]

This equation is in the form \( px + q = r \) where:

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

So the final equation representing the problem is:

\[ 30x + 50 = 140 \]
