$42 is what percent of $120?

Step-by-step explanation:

given that Mr.Hann is trying to decide how many new copies of a book to order for his students. Each book weighs 6 ounces.

So in ordered pair first coordinate represents the number of books while second will have 5 times the second coordinate.

No of books can never be negative or in fraction/decimal.

so out of the ordered pairs the genuine is only

(0,0)

A viable solution for x represents the number of books he orders and y represents the total weight of the books, in ounces

is (0,0)

(reason is number of books cannot be -3 or -0.5 or 0.5)
