<u>Correct Question</u>
In the table shown, the sum of each row is shown to the right of the row and the sum of each column is shown below the column. What is the value of L?
Answer:
L=7
Step-by-step explanation:
From the first row: 2J+K=5
Therefore: K=5-2J
From the second column, 2K+J=7
Substitute K derived above into 2K+J=7
2K+J=7
2(5-2J)+J=7
10-4J+J=7
-3J=7-10
-3J=-3
J=1
Recall: K=5-2J
K=5-2(1)=3
K=3
From the third column, J+2L=15
1+2L=15
2L=15-1=14
L=7
Therefore, the value of L=7

Answer:
Company needs to sell at least 34 tickets in order to make a profit.
Step-by-step explanation:
Given:
Rent for the space = $300
Cost per tickets = $9
Let the number of tickets sold be 'x'
We need to find the least number of tickets to be sold to make profit
Now total profit can be made if amount which is made after selling number of tickets is greater than 300.
Hence the equation can be framed as,
Solving the equation to find the value of x we get;
We will use Division property and divide both side by 9 we get;
Tickets which need to be sell cannot be in point value hence rounding to whole number we get;
Hence Company needs to sell at least 34 tickets in order to make a profit.
