Members of a school social service group hold a spaghetti dinner to raise money for orphan children. They must sell tickets at a price that will earn them more money than the cost of food. The formula for this scenario is t = n (p − c) where t = total profit earned from the event c = cost of food per plate n = number of tickets sold p = price charged for each dinner Rewrite the equation to determine the number of tickets they need to sell.

Question

Answer:

If you want to know the number of tickets sold, you have to isolate the n variable. Since n is multiplied by (p-c), you have to do the opposite to move (p-c) to the left side of the equation.

t=n(p-c)
Divide both sides by (p-c)
t/(p-c) = n

Hope this helps! :)
