Gretta has 40 raffle tickets to sell. she is required to sell at least 15 tickets. she sells the raffle tickets for $10 each.
the amount of money gretta makes from selling x raffle tickets is represented by a function.
f(x)=10x
what is the practical range of the function?
a. all integers from 15 to 40, inclusive.
b. all multiples of 10 between 0 and 400, inclusive.
c. all real numbers.
d. all multiples of 10 between 150 and 400, inclusive.

(D) All multiples of 10 between 150 and 400, inclusive. i took the test myself.

Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.

Step-by-step explanation:

We have been given the information that gretta is selling x raffle ticket by a function

f(x)=10 x

Range is the values that y takes in a particular function

Here, we will get any value which is multiple of 10 since we have a function 10 times of something whatever value we put for x we will get multiple of 10.

Hence, Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
