To find the total cost for purchasing 9 tickets on Friday with the given discount, let's follow these steps:
1. Determine the cost per ticket with no discount:
- According to the table, 3 tickets cost \[tex]$21.
- To find the cost per ticket, divide the total cost by the number of tickets:
\[
\text{Cost per ticket} = \frac{\$[/tex]21}{3} = \[tex]$7
\]
2. Calculate the discount amount per ticket on Friday:
- The discount on Friday is \$[/tex]2 per ticket.
3. Determine the cost per ticket with the discount:
- Subtract the discount from the original cost per ticket:
[tex]\[
\text{Discounted cost per ticket} = \$7 - \$2 = \$5
\][/tex]
4. Calculate the total cost for 9 tickets on Friday:
- Multiply the discounted cost per ticket by the number of tickets:
[tex]\[
\text{Total cost for 9 tickets} = 9 \times \$5 = \$45
\][/tex]
Therefore, the total cost for 9 tickets on Friday is \[tex]$45.
Enter the total cost in the box:
Total cost for 9 tickets on Friday: \$[/tex]45
