Answer:
After buying the meal and the computer game, Kristian has 43.33% of his money left.
Step-by-step explanation:
Given that Kristian buys a meal for $ 8.40, to calculate the fraction of the $ 72 after buying the computer game which cost $ 32.40 and the meal, the following calculation must be performed:
72 = 100
8.40 + 32.40 = X
72 = 100
40.80 = X
40.80 x 100/72 = X
4,080 / 72 = X
56.66 = X
100 - 56.66 = 43,333
Therefore, after buying the meal and the computer game, Kristian has 43.33% of his money left.
It can never be a square.
The given statement is false because it isn't an empty set!
<u>Step-by-step explanation:</u>
We have following sets of inequalities:

From
we get ,

Therefore solution set is x=2.
Now, for
we get ,

Therefore solution set is x>2.
For
we get ,

Therefore solution set is x<2.
Now, the union of x=2, x<2 & x>2 is -∞<x<∞. i.e. all possible values of x. And so above statement is false because it isn't an empty set!
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.
