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.

So in other words, you need to rearrange
$$t = n(p-c)$$
So n is the subject. Does that make it easier?
