Final answer:
Zachary's unit cost for one hotdog is calculated by dividing the total cost of $12 by the number of hotdogs purchased, which is 8. This results in a unit cost of $1.50 per hotdog.
Step-by-step explanation:
Zachary bought eight hotdogs at the fair and paid a total of $12 for them. To find the unit cost of one hotdog, we need to divide the total cost by the number of hotdogs. This is a straightforward division problem:
- Total cost of hotdogs: $12
- Number of hotdogs: 8
So, the calculation for the unit cost would be $12 divided by 8 hotdogs, which equals $1.50 per hotdog. Therefore, the unit cost for one hotdog is $1.50.
