Music lessons. Band members at Colchester Middle School are expected to average at least 20 min of practice time per day. One week Monroe practiced 15 min, 28 min, 30 min, 0 min, 15 min, and 25 min. How long must he practice on the seventh day if he is to meet expectations?

add up the minutes then divide by # of minutes. 

so 15+28+30+0+15+25/ 6. So 113/6.  18 5/6 minutes is your answer to your question.
