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.
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.
The problem asks to rewrite the equation to solve for the number of tickets sold, which is represented by the variable n. This means one must isolate n
