The equation that models this trip is t= 36x + 60 where t represents the total cost for the group to take the trip and x equals the number of people going. what values are appropriate for the domain? a) x=40 b) x=60 c) 0< x< 40 d) 0< x< 39

We are given

The equation that models this trip is T= 36x + 60

T represents the total cost for the group to take the trip and

X equals the number of people going

we know that

Domain is all possible values of x for which any function is defined

Since, number of people can neither be negative nor in decimals

so, x can not be negative or in decimals

now, we will check each options

option-A:

x=40

This is positive and whole number

so, this can be domain

so, this is TRUE

option-B:

x=60

This is positive and whole number

so, this can be domain

so, this is TRUE

option-C:

0< x< 40

It also includes decimals numbers

and we know that

x can not be in  decimals

so, this is FALSE

option-D:

0< x< 39

It also includes decimals numbers

and we know that

x can not be in  decimals

so, this is FALSE

maybe - definition of supplementary angles. im not sure. sorry
