The value of (x-y) is 16
Further explanation:
We have to use the given values to find the value
Given

We will use:

Simplifying by using: 
So,

As we know that x+y=4
Putting the value in equation

Dividing both sides by 4

The value of (x-y) is 16

Question 2

Sabrina should be careful of those ants and bees.
Answer:
40 Tickets
80 Tickets
Step-by-step explanation:
To find how many tickets it will take to break even, we use the formula:

Our variables are:
Fixed Cost = $200
Sales Price = $10
Variable Cost = $5
Let's plug in our values into the formula.



So the class needs to sell a total of 40 Tickets to break even.
Since we know that it takes 40 tickets to break even a $200 Fixed cost. To make a profit of $200, we simply multiply the number of tickets sold by 2.
Number of tickets for $200 profit = 40 x 2
Number of tickets for $200 profit = 80 Tickets.
So the class needs to sell 80 Tickets to make a $200 Profit.
