Final answer:
To find out the cost of 4 bags of popcorn when you know the cost of 6 bags, set up a proportion and solve for the unknown value.
Step-by-step explanation:
To find out how much you will pay for 4 bags of popcorn, you can set up a proportion using the given information. Let's use x to represent the cost of 4 bags. We know that 6 bags cost $15.36, so we have the proportion 6 bags/15.36=4 bags/x. To solve for x, we can cross multiply and then divide: 6x = 15.36 * 4. Simplifying, we get 6x = 61.44. Dividing both sides by 6, x = 10.24. Therefore, you will pay $10.24 for 4 bags of popcorn.
