Total number of tables in the cafeteria = 20
65% of the tables = [tex]\frac{65}{100} (20)[/tex]
[tex]=\frac{13}{20}(20)[/tex]
= 13
Each table has 6 chairs.
So, total number of chairs that 65% of the tables have = 13 × 6 = 78.
35% of the tables = [tex]\frac{35}{100} (20)[/tex]
[tex]=\frac{7}{20} (20)[/tex]
= 7
Each table has 4 chairs.
So, total number of chairs that the remaining 35% of the tables have = 7 × 4 = 28.
Hence, total number of chairs in the hospital cafeteria = 78 + 28 = 106.
