See a solution process below:

Explanation:

A formula for this problem would be:

#t = u + r#

Where:

#t# is the total time available - in this problem 62 minutes.

#u# is the total time used - in this problem 24 minutes.

#r# is the total time remaining - what we are solving for in this problem.

Substituting and solving for #r# gives:

#62 = 24 + r#

#-color(red)(24) + 62 = -color(red)(24) + 24 + r#

#38 = 0 + r#

#38 = r#

#r = 38#

#color(red)(38)# more minutes of music can be added to the disc.
