Answer :
Answer: 35
Step-by-step explanation:
Given : A local band is holding a concert. The price of a ticket to the concert is $15.
The band must sell enough tickets to cover at least the $525 cost of renting the gym.
Let the number of tickets sold be represented by x.
Then , the required inequality to determine how many tickets must be sold to at least cover the cost of the gym :-
[tex]15x\leq525[/tex]
Divide both sides by 15 , we get
[tex]x\leq\dfrac{525}{15}\\\\x\leq35[/tex]
Hence, the number of tickets must be sold to at least cover the cost of the gym = 35
