This equation shows how the total cost of visiting the science museum as a member is related to the number of visits.

c = v + 9

The variable v represents the number of visits to the science museum, and the variable c represents the total cost of those visits. For a member of the science museum, what is the total cost of 2 visits?

1 answer

To find the total cost \( c \) for 2 visits, we can substitute \( v = 2 \) into the equation \( c = v + 9 \).

\[ c = 2 + 9 \]

\[ c = 11 \]

Thus, the total cost of 2 visits is \( \boxed{11} \).
