Answer:
Step-by-step explanation: 800/x=100/17
(800/x)*x=(100/17)*x - we multiply both sides of the equation by x
800=5.88235294118*x - we divide both sides of the equation by (5.88235294118) to get x
800/5.88235294118=x
136=x
x=136
83% of 800=664

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.
