Final answer:
The school will make a profit of $1.32 when it sells the 11th raffle ticket.
Step-by-step explanation:
To find out how much profit the school will make when it sells the 11th raffle ticket, we can use the information given.
We know that the school makes a profit of 72 cents on every 6 raffle tickets sold.
So, we can calculate the profit per ticket by dividing 72 cents by 6 tickets: 72 cents / 6 tickets = 12 cents per ticket.
Now, we can find the profit for the 11th ticket by multiplying the profit per ticket by the number of tickets: 12 cents * 11 tickets = 132 cents.
Therefore, the school will make a profit of 132 cents, or $1.32, when it sells the 11th raffle ticket.
