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
