Statements 1 and 4 are correct. Let me know if you need more of an explanation. :)
I'd say the top one. The second and third both exceed a year. The last seems to be similar to the top, but I was taught that the dependent variable is the y axis.
(700/1200)*100 = 58.33%, rounding to the nearest 10th of à percent we get 60%
The answer is: " 40 books " .

Explanation:
____________________________________________
Let "x" equal the number of books that Jill started with. Solve for "x" :
____________________________________________
x – (1/2)x + 16 = 36 ;
1x – (1/2)) = (1/2)x ;
(1/2)x + 16 = 36 ;
Subtract "16" from EACH SIDE of the equation:
(1/2)x + 16 – 16 = 36 – 16 ;
(1/2)x = 20 ;
Multiply each side of the equation by "2" ;
2*(1/2)x = 20 * 2 ;
to get: x = 40 .
