Options : (–3, –18) (–0.5, –3) (0, 0) (0.5, 3)
Answer: (0, 0)
Explanation:
Given the following :
X = Number of books he ordered
Y = total weight of the book in ounces
Weight of each book = 6 ounces.
From the options provided,
(–3, –18) (–0.5, –3) (0.5, 3) aren't feasible options because of the following reasons.
The number of books ordered must be a whole number as it is impossible to order fraction of a book, hence, the ordered pair, (-0.5, - 3) and (0.5, 3) aren't viable solutions.
Also, the option (–3, –18) portrays a negative value and the number of books a person orders cannot be negative. Hence, the viable solution should be a positive whole number.
The only solution which seems viable is (0, 0) with x being 0 and y also. 0
If x = Number of books he ordered = 0
Ultimately, the total weight of the book in ounces will be (weight per book * number of books ordered)
= (6 ounces × 0) = 0
Hence, (0,0)
