Ответ:
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.
