Answer:
18. C
19.A
20. C
Step-by-step explanation:
18.
x< 15 where x is the average that each person contributes.
This gives 3x <45, limiting the gift basket's total cost to < $45. (Actually ≤ 14.99 per person, so max cost is $44.97.
19. simple algebra
a <= -4 + 7
a <= 3
20.
since u divide and the co efficient is negative u flip the sign
-3m<15
m>-5
you have to simplify it
then isolate the variable
then you will get x=6
Consider this option (see the attached picture). Note, that every domain of the function is marked by green.
