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

\newline

c = v + 16

\newline

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

1

visit?

\newline

\$

_____

Identify variable for $1$ visit: Step $1$ : Identify the variable that $1$ visit corresponds to. $\newline$ $v$ represents the number of visits to the science museum. So, $1$ visit gives the value for $v$ .
Substitute value for $v$ : Step $2$ : We know that $v = 1$ . $\newline$ Plug in the value for $v$ in $c = v + 16$ . $\newline$ $c = v + 16$ $\newline$ Substitute $v$ with $1$ . $\newline$ $c = 1 + 16$
Solve for c: Step $3$ : $c = 1 + 16$ . $\newline$ Solve for c. $\newline$ $c = 1 + 16 = 17$
