What is a system of equations for the following situation? A group of 12 people went to see a movie. The cost to go to the movie is $10 for an adult and $6 for a child. The total cost for the group was $100.

Answer:
the second option
Step-by-step explanation:
since 12 people went in total, adults plus children would equal this value.
Together, they all paid 100 dollars. Therefore, since adults are 10 dollars and children are 6, multiplying these charges by the amount that showed up will give you 100 dollars.
