Answer:
168
Explanation:
Gift Cards sold by Ernie = 66
Gift cards sold by Hessie = 24
Gift Cards sold by Makayala = 78
Common Factor = 6
66 = 6 x 11
24 = 6 x 4
78 = 6 x 13
The total number of gift cards sold is the sum of each person, that being 66 + 24 + 78 which equals 168
Total number of gift cards that all three sold = 168
