The correct answer is (C).
Getting to the Answer:The mean of a group of numbers is the sum of the values divided by the number of values. There are five values in the table that represent the number of pesos spent each day, and their sum is 250 + 100 + 150 + 100 + 400 = 1000. Thus, the mean number of pesos Anton spent each day is 1000/5 = 200.
(A) Incorrect: this is the mode, since there were two days in which Anton spent 100 pesos
(B) Incorrect: this is the median, not the mean
