Based on the given table, you can notice that the rate of change of the number of pages read related to the number of hours, is 120 pages each 3 hours.
Then, to determine the number of pages read for 15 hours, consider that after 12 hours Sarah read 480 pages. After 3 more hours, that is, for 15 hours of reading, Sarah read 120 pages more, that is, she read 480+120=600 pages.
Hence, the answer is 600

Answer:
Step-by-step explanation:
5x + 2y = -3
3x + 3y = 9
15x + 6y = -9
-15x - 15y = -45
-9y = -54
y = 6
5x + 2(6) = -3
5x + 12 = -3
5x = -15
x = -3
(-3, 6)
