Billy needs to read 500 minutes this week for his English class. He is going to read 6 days. If he already reads 15 minutes every day, how many additional minutes does he need each day to read at least 500 minutes?
Firstly, you need to work out how many minutes he is already reading for; in this case, you do
#15 xx 6 = 90#
Then to work out how many minutes more he needs to read, you do
#500 - 90 = 410#
Finally, to work out how many minutes per day, you just divide
#205/3 = 68. bar(3)#
Hopefully this helped...
