Respuesta :
Its quite simple. Its just subtraction.
18 hotdogs - 12 hotdog buns = 6 hotdug buns still needed
18 hotdogs - 12 hotdog buns = 6 hotdug buns still needed
18-12= 6
6 is the amount of hotdog buns needed.
You subtract 12 from 18 because you already have that amount of buns and need to see how many you need to get.
