To find the total cost for 5 children and 2 adults using the expression \(12c + 15a\), we can substitute \(c\) with 5 (the number of children) and \(a\) with 2 (the number of adults).
\[
\text{Total Cost} = 12c + 15a
\]
Substituting the values:
\[
\text{Total Cost} = 12(5) + 15(2)
\]
Now, calculate each term:
\[
12(5) = 60
\]
\[
15(2) = 30
\]
Now, add the two results together:
\[
\text{Total Cost} = 60 + 30 = 90
\]
Therefore, the total cost for 5 children and 2 adults is **$90**.
