The expression 20a + 13c is the cost for a adults and c students to enter the Miami Science Museum. Find the total cost for four adults and 24 students.

Answer 1

To find the total cost for four adults and 24 students, we first need to substitute a = 4 and c = 24 into the expression 20a + 13c.

Total cost = 20(4) + 13(24)
Total cost = 80 + 312
Total cost = 392

Therefore, the total cost for four adults and 24 students to enter the Miami Science Museum is $392.
