Respuesta :
B is the correct answer because 50 tickets times 7 dollars per ticker equals 350, and 350-350 equals 0. 50 Tickets must be sold to cover expenses
We are given
Tickets to the senior class play cost $7
Let's assume total number of tickets sold is n
so, total tickets sold =7*n
[tex] SP=7n [/tex]
we are given
Production expenses for costumes and sets are $350
so, [tex] CP=350 [/tex]
we know that
profit =SP-CP
[tex] P=7n-350 [/tex]
the number of tickets that must be sold to cover expenses when profit is zero
so, we can set p=0
and then we can solve for n
[tex] 0=7n-350 [/tex]
[tex] 7n=350 [/tex]
[tex] n=50 [/tex]
so, option-B...........Answer
