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

To find the total cost for four adults and 24 students, we need to substitute the values of "a" and "c" into the expression.

Given:
Number of adults = 4
Number of students = 24

Substituting into the expression 20a + 13c:
Total cost = 20(4) + 13(24)

Calculating:
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.

To find the total cost for four adults and 24 students to enter the Miami Science Museum with the given expression, we need to substitute the values into the expression and then calculate.

Given:
Expression: 20a + 13c
Number of adults: 4
Number of students: 24

Let's substitute the values into the expression:

Cost for adults: 20a
Cost for students: 13c

Substituting the values:
Cost for four adults: 20 * 4 = 80a
Cost for 24 students: 13 * 24 = 312c

Now, to find the total cost, we need to add the cost for adults and the cost for students:

Total cost = Cost for four adults + Cost for 24 students
= 80a + 312c

Therefore, the total cost for four adults and 24 students to enter the Miami Science Museum is 80a + 312c.

To find the total cost for four adults and 24 students to enter the Miami Science Museum, we can use the expression 20a + 13c, where "a" represents the number of adults and "c" represents the number of students.

Given that there are four adults and 24 students, we can substitute these values into the expression.

Let's first calculate the cost for four adults:
20a = 20 * 4 (as there are four adults)
= 80

Next, let's calculate the cost for 24 students:
13c = 13 * 24 (as there are 24 students)
= 312

Finally, to find the total cost, we need to add the cost for adults and students:
Total Cost = Cost for adults + Cost for students
= 80 + 312
= 392

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