Word Problem 8

Problem 8: There are 15 tables in Camille’s Cafe. Some of those tables can seat 6 people, and the rest of them can only seat 4 people. If a maximum of 76 people can be seated at Camille’s Cafe, how many 6-people tables does the cafe have?

Solution:

Let there are ‘x’ 6-people tables and ‘y’ 4-people tables

Total tables are 15, so;

x+y=15 ---(1)

If 6 people sit on x 6-people table and 4 people sit on all y 4people table then it should accommodate 76 people in total ;

6x+4y=76----(2)

Solving these eqs simultaneously we get;

2x=16

x=8

so there are 8 6-people table.

Put x value in eq 1

8+y=15

y=7

so there are 7 4-people tables.
