## Elementary Technical Mathematics

Total number of tables is found by adding the different types of tables: Total tables= 10+12=22 As each server can serve at most 6 tables, divide the total tables by 6 to find number of servers required: $22\div6=3\frac{2}{3}$ As there cannot be 2/3 of a server the above number is rounded up to the nearest whole number to find least number of servers required. Thus, least number of servers required= 4
