Explanation:

the answer is the factor of n : 70.

with every sold ticket the charity raises $70.

add on :

to break even (to have at least 0 or more dollars as profit) they need to sell at least

70n - 1500 = 0

70n = 1500

7n = 150

n = 150/7 = 21.42857143...

that means, since they can't sell parts of tickets, they need to sell at least 22 tickets.
