*** ***raul is selling coupon books. he started with 50 coupon books and has already won a prize for selling at least 10 coupon books. the total amount of money raul will make from selling x coupon books as represented by a function. f(x) = 20xwhat is the practical domain of the function? a) all real numbers b) all multiples of 20 between 0 and 1000, inclusive c) all integers from 10 to 50, inclusive d) all integers from 0 to 50

c) All integers from 10 to 50, inclusive

Step-by-step explanation:

Rauls is selling coupon books.

He started with 50 coupon books and has already won a prize for selling at least 10 coupon books. It means He has a maximum value of 50 coupons and he already sold 10 coupons.He can sell from 10 coupons to 50 coupon books.

The total amount of money Raul will make from selling x coupon books as a function is

f(x) = 20x

The domain of this function is all Real numbers. However, we need a practical domain.Coupon books are integer numbers, 1, 2, 3 we will not have a half book. So, Coupon right now can vary from 10 coupon books to 50 coupon books. It means x can vary from 10 to 50, only integer values and inclusive 10 and 50.

Finally, the answer is C) all integers from 10 to 50, inclusive. 

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
