Answer:
First option: 2
Step-by-step explanation:
Check each answer:
8 < x(7-x)
8 < 2(7-2)
8 < 2(5)
8 < 10
True
8 < x(7-x)
8 < 8(7-8)
8 < 8(-1)
8 < -8
False
8 < x(7-x)
8 < -1(7-(-1))
8 < -1(7+1)
8 < -1(8)
8 < -8
False
8 < x(7-x)
8 < 0(7-0)
8 < 0
False
Therefore, 2 is the only correct solution out of the given answer choices.
The expression that represents the cost of y books is 12y + 3.
Given that,
- The charge for the first copy of the book is $15.
- For each extra copy, the charge is $12.
- Here we assume the number of books be y.
Now based on the above information, the expression should be
= 12y + (15 - 12)
= 12y + 3
Therefore we can conclude that option F is correct.
