Th expression 12c+15a represents the total coast for group of children ad adults to go bowling. The variable C represents the number of children attending. The variable A represents the number of adults attending. What is the total cost for 5 children an d 2 adults?

Answer 1

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.
