p dollars for the first 5 miles of any trip plus 0.1*p dollars for each additional mile or fraction of a mile.
Given the statements
(1) The moving service charged a total of 3.3p dollars for the trip.
First 5 miles cost = p
Remaining amount = 3.3p − p = 2.3p
Cost per additional mile = 0.1p
Remaining miles = 2.3p/0.1p = 23 miles
Total miles = 23 + 5 = 28 miles
Trip was not more than 30 miles.
(2) The moving service charged a total of $132 for the trip.
First 5 miles cost = p
Total cost = p +0.1p⋅⌈x−5⌉ = 132
=> p =132/(1+0.1n) [Let ⌈x−5⌉ = n]
Lets say n = 25 => Total miles = 25+5 = 30
p = 132/(1+0.1*25) = 37.71 > 30
Lets say n = 25 => Total miles = 24+5 = 29
p = 132/(1+0.1*24) = 38.82 > 30
So in both cases of being lesser and greater than 30 miles is possible
A. Statement (1) alone is sufficient, but statement (2) alone is not
