Question

Esmeralda likes to listen to music while she works out. She had a playlist on her mp3 player that lasted 40 minutes,but she accidentally deleted 25%of the music. Does Esmeralda have enough music left on her playlist for 30 minutes workout

Answer 1

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%.

$75\%=75/100=0.75$

Find out how many minutes represent 75% of 40 minutes

Multiply 40 by 0.75          

$40(0.75)=30\ minutes$

therefore

Esmeralda has enough music left in her playlist for a 30 minute workout
