Final answer:
The cost of 5 movie tickets is $70.60 and the cost of 11 movie tickets is $155.32.
Step-by-step explanation:
Given that 3.4 movie tickets cost $48, we can calculate the cost of a single movie ticket by dividing $48 by 3.4. The cost of a single movie ticket is $48/3.4 = $14.12 (rounded to two decimal places).
a. To find the cost of 5 movie tickets, we multiply the cost of a single ticket by 5. Therefore, the cost of 5 movie tickets would be 5 * $14.12 = $70.60.
b. Similarly, to find the cost of 11 movie tickets, we multiply the cost of a single ticket by 11. Thus, the cost of 11 movie tickets would be 11 * $14.12 = $155.32.
