Final answer:
To find the number of Capulets and Montagues, set up a system of equations using the given information, solve the system of equations, and find the values of x and y. There are 6 Capulets and 16 Montagues.
Step-by-step explanation:
To solve this problem, we can set up a system of equations using the given information. Let's assume that there are x Capulets and y Montagues.
From the information given last year, we know that each Capulet wrote 4 essays and each Montague wrote 6 essays, and the total number of essays written by both families was 100.
This can be represented by the equation 4x + 6y = 100.
Using the information given this year, we know that each Capulet wrote 8 essays and each Montague wrote 12 essays, and the total number of essays written by both families was 200.
This can be represented by the equation 8x + 12y = 200.
Now we can solve this system of equations to find the values of x and y.
By solving these equations, we find that x = 6 and y = 16.
Therefore, there are 6 Capulets and 16 Montagues.
