Answer: Each table can seat 5 people and each booth can seat 10 people.
Explanation:
According to the first plan, there are 12 tables and 25 booths, and the total number of people seated is 310. This can be written as:
12x + 25y = 310
According to the second plan, there are 11 tables and 23 booths, and the total number of people seated is 285. This can be written as:
11x + 23y = 285
Multiplying the first equation by 11 and the second equation by 12, we get:
132x + 275y = 3410
132x + 276y = 3420
Subtracting the second equation from the first equation, we eliminate 'x':
275y - 276y = 3410 - 3420
-y = -10
Dividing both sides of the equation by -1, we get:
y = 10
'
Substituting this value of 'y' into the first equation, we can solve for 'x':
12x + 25(10) = 310
12x + 250 = 310
12x = 310 - 250
12x = 60
x = 60/12
x = 5
Therefore, each table can seat 5 people, and each booth can seat 10 people.
