12 archeology students and 4 teachers went on a field trip to a dinosaur museum. Student tickets cost $1 each, and adult tickets cost $3 each. How much did the museum tickets cost in all?
The cost of the 12 student tickets is 12 * $1 = $<<12*1=12>>12.
The cost of the 4 teacher tickets is 4 * $3 = $<<4*3=12>>12.
Adding the cost of the student and teacher tickets, the museum tickets cost $12 + $12 = $<<12+12=24>>24 in total.
