Solution:
All but 50 were sold.
Total 1000. Therefore, sold plants = 1000 - 950 = 50.
30% sold at 25% discount:
30% of 950 = 3/10 * 950 = 285.
Price = 25% discount on 12. = (100-25)% of 12 = 75% of 12 = 9.
Total revenue here = 285 * 9 = 2565
Remaining sold at full value ->
70% sold at 12 dollars.
665 sold at 12
Revenue = 665 * 12 = 7980
Total revenue = 7980 + 2565 = 10545 = C

It's asking for what MUST be true. If X, then Y follows.
If -6 <= n <= 10, then n MUST be greater than -8. Every value that n could take between -6 and 10 is greater than -8.
For A), n could be less than 8, but does not have to be. It could be 9 or 10.
For B), n could be -6, but it does not have to be. It could be 0.
For D), n could be within this range, but it could also be 7, 8, 9, or 10.
C

C
Is the answer to this one E?
A) n <8 may entail values < -6 which doesn't suit the domain given
B) n could= -6 or 10 or 6
C) n > -8 may entail -7 or values > 10
D) -10 < n < 7 doesn't fit the domain given
?
A) n <8 may entail values < -6 which doesn't suit the domain given
B) n could= -6 or 10 or 6
C) n > -8 may entail -7 or values > 10
D) -10 < n < 7 doesn't fit the domain given
?
