The expression 25c+48a

Question

represents the total cost for a group of children and adults to attend the amusement park. The variable c
represents the number of children attending. The variable a
represents the number of adults attending. What is the total cost for 12 children and 4 adults?

Answer 1

To find the total cost for 12 children and 4 adults using the expression \( 25c + 48a \), we can substitute \( c = 12 \) and \( a = 4 \) into the expression:

\[ 25c + 48a = 25(12) + 48(4) \]

Now, calculate each term:

1. Calculate \( 25(12) \): \[ 25 \times 12 = 300 \]

2. Calculate \( 48(4) \): \[ 48 \times 4 = 192 \]

Now add the two results together:

\[ 300 + 192 = 492 \]

Therefore, the total cost for 12 children and 4 adults is $492.
