Answer: 2.50$
Step-by-step explanation:
lets use x The sum of that and 6 is 1/2 x + 6
Ten times that is 10 (1/2 x + 6)
The question says that's 8.
So 10 (1/2 x + 6) = 8
Divide each side by 10 : 1/2 x + 6 = 0.8
Subtract 6 from each side: 1/2 x = - 5.2
<span>Multiply each side by 2 : x</span><span> = - 10.4</span>
Its okay, the first half is completely irrelevant. All that matters is x and y. y = 16, because y is how much space the books take up. x = 8, since x is the number of books. All you have to find is the proportions. It is most likely talking about the proportions of the books, so you would need to find the length if each book. You know they will all be the same because it was previously mentioned each book is the same size. So the equation is:

Since 16/8 is 2, you would get 2in/book.
Hope that helps!
June has 30 days
so 70% of 30 were sunny
0.70(30) = 21 days <==
