Question

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 everyday, how many additional minutes does he need each day to read at least 500 minutes? Along with the answer, write the inequality as well.

Answer 1

Explanation:

So you break it down first.

Total needed to be read: 500 minutes

Days reading: 6

Unit Rate (what he already reads a day): 15 minutes

Variable (for days): d

Next, you need to work out how many minutes he is already reading for; in this case, you do 15 multiplied by 6 which is 15 × 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 410 by the 6 days he's going to read for. So you get the answer of 205/3 = 68.3 or 63 and 16/3.

Hope this helped a little

Answer 2

500/6=83.33
83.33-15=68.33
that's what I know how to do for certain.
then the inequality (I'm guessing), might be 15+6x<=500
(less than or equal to)
