The table shows how the total cost of a field trip depends on the number of students. what is a rule for the total cost of the tickets? give the rule in words and as an algebraic expression

12 × n + 150

Step-by-step explanation

Total cost of a field trip depending on the number of students has been given in the table attached.

We have to draw a rule for the total cost of the tickets.

As we can see for 20 students total cost of the ticket is (12 × 20) + 150

by this table we can write the rule in word form as

number of students multiplied by twelve then one hundred and fifty is added to the product.

Algebraic expression will be

12 × n + 150

Here,  n = number of students.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
