Answer:
Inequality is
Solution is C: t > 82
Step-by-step explanation:
Let the number of tickets = t
It is given that the committee earns $4 per ticket. That is, they earn dollars.
Also, the committee earns $72 from the bake sale.
So, the total income is dollars.
Since, the dance will cost $400.
So, the total earning must be greater than $400.
Thus, the inequality for the situation is given by, .
So, on solving, we have,
i.e.
i.e. t > 82.
Thus, the solution of the inequality is
Hence, option C is correct.
