Question

A theme park charges different admission prices according to children's ages. Its price scale can be described by the function graphed above. Select the only false statement based on the information provided in this graph.Question 9 options:A) The price of a ticket for a nine-year-old child is $18.B) The price of a ticket for a four-year-old child is $8.C) The price of a ticket for an eight-year-old child is $8.D) The price of a ticket for a twelve-year-old child is $24.

Answer 1

Given the question in the question tab, the following are the solution steps to get the false statement'

Step 1: We interpret the graph

For the selected information, this implies that the age ranges from 0 to 8. The hollow dots means the point is not included while the black dot means the point is included. so this means:

`0\le x<8`

The image above can be interpreted as:

`8\le x<12`

The third image can be interpreted as:

`12\le x<18`

Step 2: We test the statements in the options to confirm if they are true or false

Option A is true because the price of the ticket for a nine-year-old child is $18 from the interval given in step 1

Option B is true because the price of the ticket for a four-year-old child is $8 from the interval given in step 1

Option C is false because the point 8 was not included in the age section for the corresponding price of tickets. Hence, the price of a ticket for an eight-year old is $18

Option D is true because it can be seen from the interval that the price of ticket for a twelve-year old child is $24
