Answer:

Step-by-step explanation:
At least 6 hours means that the people took at least 6 hours and at most any number that is greater than 6. Here the greatest no. is 10.
<em><u>So, the range for this will be 6-10</u></em>
No. of People who sleep for 6-8 hours = 9
No. of People who sleep for 8-10 hours = 3
No. of People who sleep for 6-10 hours = 9+3
=> 12 people
If Peter spends 20% of his salary on expenses, and his salary is $30,000, then all we need to do is find 20% of 30,000.
We can do this by converting 20% to a fraction or decimal. We'll do fraction because I think it is easier to see.
20% = 20/100 = 2/10 = 1/5
So we need to find 1/5th of 30,000
1/5 x 30,000 = 30,000/5 = 6,000
Therefore, Peter has $6,000 to spend on expenses.
