It is 20 because if u divide 78 by 3.75 ( 3 3/4 ) than equals 20.8
I think what may be confusing is the fact that they also list two three digit numbers with two decimal places each. Since the number is greater than 4.49 with only two digits, it can't be 4.5 since the tenths place is odd. Same goes for less than 4.71. So the only answer would be 4.6--two digits, even tenths place, greater than 4.49 and less than 4.71.
Just some logical thinking, I guess. I think they were trying to trick you on this one.
Good luck.
Answer:
C = 14
Step-by-step explanation:





If we graph the inequalities, the solution set of the constraints is the shaded area (see attached diagram).
The vertices of the shaded area are (0, 20), (6, 8) and (18, 0)
To determine the minimum value of C, substitute the values of x and y of each vertex into C = x + y:
at (0, 20): C = 0 + 20 = 20
at (6, 8): C = 6 + 8 = 14
at (18, 0): C = 18 + 0 = 18
Therefore, the minimum value is at (6, 8) ⇒ C = 14
