Melissa practice the piano for 30 min each day and the flute for 15 min each day. She is playing both the piano and the flute in a recital 8 days from now.How many minute will she practice both instruments before the recital?
Melissa will practice 360 minutes both instruments before the recital. I suppose you must multiply 30 by 8 and 15 by 8 and you get 240 for 30 by 8. And 120 for 15 by 8. 240 plus 120 equals 360
