is it the average of first four days or the four months ??
Because the average of 4 months is x and the 1st month is 1.5x, so the answer is 1.5(1 1/2)
Because the average of 4 months is x and the 1st month is 1.5x, so the answer is 1.5(1 1/2)

Call the number of visitors on the 2nd x. Then, the number of visitors on the first was 1.5x. The number of visitors on the 3rd and 4th were each \(\frac{3}{4}x\).
The average number of visitors per day, then, is: \(\frac{1.5x+x+0.75x+0.75x}{4} =\frac{4x}{4} = x\)
The number of visitors on the 1st of the month was 1.5x, so that is 1.5 times the average number of visitors, x. Choice (C) is correct.
