Question

3. To earn a weekly allowance, Neal has to average doing homework for at least 45 minutes each day for 5 days. This week, Neal has spent 26 minutes, 57 minutes, 33 minutes, and 41 minutes on homework so far. How much time will he have to spend on his homework on Friday to be able to earn his weekly allowance?

Answer 1

Neal has to work 68 more minutes

Explanation:

Hey there!

In order to find the answer to this question, we must first find the average amount of work he as done so far.

He has spent 26, 57, 33, and 41 minutes so far on homework

In total, he has worked 157 minutes in total

Now to find how much more minutes he has to do, we need to subtract the total amount of minutes he has to do all week and the amount of time he has already worked

In this case, Neal has to work at least 225 minutes in 5 days and he already did 157 minutes of work

Now we subtract:

225 - 157 = 68

This means, Neal has to work 68 more minutes to have an average of 45 minutes each day for 5 days
