Final answer:
To determine the amount that each person will pay, we can use the concept of ratios. The fractions representing each person's contribution can be found by dividing their individual amount by the total amount. Using these fractions, we can calculate the amount each person will pay.
Step-by-step explanation:
To determine the amount that each person will pay, we can use the concept of ratios. Let's say there are four people: Hannah, Lizzy, Emma, and Bill. We can set up a ratio using their given amounts: Hannah: 28.77, Lizzy: 29.17, Emma: 26.28, Bill: 31.27. The total amount can be found by adding these amounts together: 28.77 + 29.17 + 26.28 + 31.27 = 115.49.
To find the fraction that represents each person's contribution, divide their individual amount by the total amount. For example, Hannah's fraction would be 28.77/115.49. Simplifying this fraction, we get 0.2499. Similarly, Lizzy's fraction would be 29.17/115.49, which simplifies to 0.2528. Continuing this process for Emma and Bill, we can find their fractions as well.
Using these fractions, we can calculate the amount each person will pay. Multiply each person's fraction by the total bill amount of $100 and round to two decimal places to get the final amount each person will pay.
