At an amusement park, a person spends $30 on admission and food, and then goes on r number of rides that cost $2 each. a. Write an equation to represent the total amount A spent at the amusement park if a person goes on anywhere from 0 to 5 rides.

b. Represent the relation as a table, as a graph, and as a mapping diagram.

c. Find the domain and range and then determine whether the relation is
a function or not.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
