Question

band members at Colchester midedle school are expected to average at least 20 min of practice per day. One week Monroe praticed 15 mi, 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?

Answer 1

So to solve this, you will need to set up an equation where the average of the given times + x is equal to 20 minutes\[(15+28+30+0+15+25+x)/6=20\]

Answer 2

I think you should divide by 7 instead of 6 because there are 7 days total

Answer 3

Yes, sorry
