Answer:
9 small packs sold and 4 large packs sold
Step-by-step explanation:
Let's S be the number of small pack and L be the number of large pack. We have
S + L = 13 packs as the total number of hotdog packs
6S + 12L = 102 packs as the total number of hotdogs
We can divide both sides of the equation above by 6 then
S + 2L = 17
The subtract the S+L = 13 equation from this equation we get
S + 2L - S - L = 17 - 13 = 4
L = 4 packs
then S = 13 - 4 = 9 packs
So there were 9 small packs sold and 4 large packs sold
