Question

2. The school PTA is sponsoring a dance. They decide to price student tickets at $6.00. It will cost the PTA $250.00 to put on the dance. How many tickets will the PTA need to sell in order to make a profit?​

Answer 1

Answer:

The PTA must sell 42 tickets to make a profit.

Step-by-step explanation:

To solve this problem, we will have to construct an inequality in which $250 is less than our solution.

Let $s$ = student tickets

Since each student ticket is priced at $6.00, the money raised by the student tickets can be represented by the expression:

$6s$

Since it will cost the PTA $250.00 for the dance, the profit will have to be equal to anything greater than $250.00.

Set up your inequality:

$250$

Divide both sides of the inequality by the coefficient of $s$, which is $6$:

$41.7=s$

As you can see, we are left with a decimal, but we will have to round to the nearest whole number as the tickets can only be represented as whole numbers:

$42=s$

Therefore, the PTA must sell 42 tickets in order to make a profit.

You can check your work by substituting the solved value for the tickets into the inequality:

$250$

$250$

$250$

And since $252 is greater than $250 (represents a $2 profit), our solution is correct.

Answer 2

Answer:

42 tickets.

Step-by-step explanation:

To make a profit, the PTA will need to earn at least $251, because it spent $250 on the dance. so we can divide 251/6 = 41 remainder 5, which means we need to sell 42 tickets.
