Question

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.
a. n*t=(p-c)
b. n=t/p-c
c. t/n=(p-c)
d. p-c/t= 1/n

Answer 1

b. n=t/(p-c)

Answer 2

thanx

Answer 3

just divide t by (p-c) to leave n by itself
