Answer:
Explanation:
Total number of tables = 7
number of trays on each table = 8
number of trays sold from each table = 2
Total number of remaining trays on each table = 8 - 2 = 6
total number of remaining trays on 7 tables = 7 x 6 = 42
total number of trays on 7 tables = 7 x 8 = 56
total number of trays sold on 7 tables = 2 x 7 = 14
