Answer:
The sum of the digits in the mystery year is 9
Explanation:
Let me try to help you
given the number of packages of hot dogs is d
given the number of packages of buns is b
so the total of hot dogs = total of buns
=> 8d = 6b or 4d = 3b
The number can be only integers like 1, 2, 3, 4, 5
So the smallest integer for d is 3 and b is 4
If you buy 3 packages of hot dogs, the number of hot dogs is 3 x 8 = 24
If you buy 4 packages of bun, the number of buns is 4 x 6 = 24
Divide #hot dogs by #packages of buns
So 24/4 = 6
Divide the result by 1/3
6 / (1/3) = 18
Sum of the digits
1 + 8 = 9
Hope this helps
