Answer:
Esmeralda has enough music left in her playlist for a 30 minute workout
Step-by-step explanation:
we know that
If Esmeralda accidentally deleted 25% of the music, then the percentage of music left in her playlist equals 100%-25%=75%.
[tex]75\%=75/100=0.75[/tex]
Find out how many minutes represent 75% of 40 minutes
Multiply 40 by 0.75
[tex]40(0.75)=30\ minutes[/tex]
therefore
Esmeralda has enough music left in her playlist for a 30 minute workout
