The auditorium will be full after 80 minutes
The total number of seats in the auditorium is the sum of all the people in the auditorium when it is full
Total number of people in the auditorium = 300
Every 10 minutes,15 people leave and 40 people sit down
Number of people joining the room every 10 minutes = 40 - 15
Number of people joining the room every 10 minutes = 25
The number of people originally in the room = 100
Number of people remaining for the auditorium to get full = 300 - 100
Number of people remaining for the auditorium to get full = 200
Number of times 25 people join the auditorium = 200/25
Number of times 25 people join the auditorium = 8
Since 25 people join every 10 minutes for 8 different times:
Time taken for the auditorium to be full = 10(8)
Time taken for the auditorium to be full = 80 minutes
Therefore, the auditorium will be full after 80 minutes

In recent year, the total receipts for the US federal government were $2154 billion. The total outlays were $2472 billion. The deficit was $318 billion. What would the deficit have been, if there had been a 2% decrease in total receipts
If there had been a 2% decrease in total receipts, the new deficit would be $361.08 billion.
If there had been a 2% decrease in total receipts, the new total receipts would be:
New total receipts = $2154 billion - (2% of $2154 billion)
New total receipts = $2154 billion - $43.08 billion
New total receipts = $2110.92 billion
The total outlays would remain the same at $2472 billion.
So, the new deficit would be:
New deficit = New total outlays - New total receipts
New deficit = $2472 billion - $2110.92 billion
New deficit = $361.08 billion
Therefore, if there had been a 2% decrease in total receipts, the new deficit would be $361.08 billion.

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. Let m represent the number of magazines and b represent the number of books. Which equation models the situation?
Answer:
3.95m + 8.95b = 47.65
Step-by-step explanation:
Since Hugh paid $3.95 for every magazine, m would be multiplied by 3.95
Since he also paid $8.95 for every book, b would be multiplied by 8.95
All of this will eventually add up to a sum of 47.65

since(a= b- 2)
5(b-2) -8 = 2b
5b -10 - 8 = 2b
3b -18 =0
3b=18;b=6
since b =6
a= 6-2 ; a= 4
