Answer:
Maleka's method
Step-by-step explanation:
Maleka's method is unbiased because He or She has a list of all of the high school students at that school and chooses the tenth one. It can't be Tony's either because it is just his class which is biased.
Let x be the price for each night and y be the price for each meal. Then, express the statements into mathematical equations:
Choice A: 3x + y = 250
Choice B: 3x + 6y = 330
Subtract both equations, the difference would be -5y = -80
-5y = -80
y = -80/-5
y = $16 per meal
3x + y = 250
3x + 16 = 250
3x = 250 - 16
3x = 234
x = 234/3
x = $78 per night
The answer is D.
