Hometown Buffet has tables that can seat 6 people and booths that can seat 4 people. The restaurant has 38 seating units for seating a total of 188 people. How many tables and booths are at the restaurant?

Respuesta :

There are 18 tables and 20 booths are at the restaurant

Solution:

Let "x" be the number of tables

Let "y" be the number of booths

The restaurant has 38 seating units

Therefore,

x + y = 38

x = 38 - y ------- eqn 1

Hometown Buffet has tables that can seat 6 people and booths that can seat 4 people

Total of 188 people

Therefore,

6x + 4y = 188 ------ eqn 2

Substitute eqn 1 in eqn 2

6(38 - y) + 4y = 188

228 - 6y + 4y = 188

2y = 40

y = 20

Substitute y = 20 in eqn 1

x = 38 - 20

x = 18

Thus there are 18 tables and 20 booths are at the restaurant
