Answer:

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.

Answer:

-----×1/72

Step-by-step explanation:

The order of operations says do these operations in order left to right. Please note that ÷ means the same as / unless you define it otherwise in your problem statement.

If you intend the ÷ symbol to be used to indicate everything to its left is divided by everything to its right, it is appropriate to use parentheses for that grouping, as in ...

(-----×1/4)÷(6×3/9) = (-----×1/4)÷2 = -----×1/8

_____

Here, we're going to evaluate what you have written according to the usual rules as described above.

(-----×1/4)÷6×3/9 = -----×1/24×3/9 = -----×(3/24)/9

= -----×1/8/9

= -----×1/72

Comment on the arithmetic

Fractions are multiplied and divided in the usual way:

a/b×c = (a×c)/b

a/b/c = (a/b) × (1/c) = a/(b×c)

___

Comment on fractions and parentheses

Please note that parentheses are required on any numerator or denominator that consists of anything other than a single number or variable. (The exception is the case where the numerator is a product, because a·b/c = (a·b)/c with or without the parentheses.)
