Josef is on a planning committee for the eighth-grade party. The food, decoration, and entertainment costs a total of $350. The committee has $75 already. If the committee sells the tickets for $5 each, at least how many tickets must be sold to cover the remaining cost of the party?

At least 55 tickets must be sold to cover the remaining cost of the party.

Step-by-step explanation:

Total money needed for the party = $350

The money already with the committee = $75

Now, the money yet to be collected = Total Party Budget - Money present

= $350 = $75 = $275

Now, the cost of 1 ticket = $5

Let us assume the number of tickets sold to cover the cost of party = m

⇒ The cost of m tickets = 5 m

The renaming cost = Total cost of m tickets

or, 5 m = $275

⇒ m = 275/5 = 55

or, m = 55

Hence, at least 55 tickets must be sold to cover the remaining cost of the

party by Josef.
