Gary is selling paperback and hardcover books at a yard
sale. he charges $2 for each paperback. he earned $10
in sales of hardcover books. he earned $20 selling books
at the yard sale. how many paperbacks did he sell?

Gary sold 5 paperback books

Step-by-step explanation:

each book is equal to $2 and $10 were made in Hardcover

So that only leaves us with ten unaccounted dollars

5x=10

Each book or (x) in this case is two dollars

so it will come out to be five books

b

step-by-step explanation:

the word superfluous means unnecessary

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
