Acharity organization had a fundraiser where they sold each ticket for a fixed price. after selling 200 tickets, they had a net profit of 12,000. they had to sell a few tickets just to cover necessary production costs of 1,200.

Y = 66x - 1200 will be the equation.

Step-by-step explanation:

This question is incomplete; Here is the complete question.

A charity organization had a fundraiser where they sold each ticket for a fixed price. After selling 200 tickets, they had a net profit of $12,000. They had to sell a few tickets just to cover necessary production costs of $1200.

       Let Y represent the net profit (in dollars) when they have sold c tickets. Complete the equation for the relationship between the net profit and the number of tickets sold.

If the selling price of one ticket is $x, then selling price of 200 tickets

= $200x

Since production cost of the tickets = $1200 and profit earned is $12000

Therefore, Profit = Selling price of x tickets - production cost

12000 = 200x - 1200

200x = 13200

x = $66

Now we can rewrite the equation for c tickets sold and profit earned $Y

Y = 66c - 1200

y=66x-1,200

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
