The expression 25c + 48a represents the total cost for a group of childern and adults to attend the amusement park. The variable c represents the number of childern attending. The variable a represents the number of adults attending. What is the total cost for 12 childern and 4 adults?
To find the total cost for 12 children and 4 adults, we substitute c = 12 and a = 4 into the expression:
25c + 48a = 25(12) + 48(4) = 300 + 192 = 492
Therefore, the total cost for 12 children and 4 adults is $492.
