Answer: 16 percent
Step-by-step explanation:
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
Answer: $1.50
Step-by-step explanation:
The item's normal price is $15.
Han uses a 10% off coupon so he saves 10% which is:
= 15 * 10%
= $1.50
He therefore bought the item for $8.50.
14 > 10
all the numbers that bigger than 10 can replace x
