Y - the money he still owes,
x - the number of months ( from x = 0 to x = 18 ):
y = 2,016 - 112 x
Let's say the number of days library book is late is X, and the total fee is Y.
Liability charges $0.30 dollars as a fee for being 1 day late,
For being 1 day late, fee charge is: 1* $0.30
So, for X days the charge would be: X*$0.30.
Total charge for being X days late is Y, Which means: Y= 0.30 * X.
Now We would have to check all the viable solutions in the answer to see if they satisfy the equation Y= 0.30 * X
Option
one(-3, -0.9) and two (-2.5, -0.75) Would not be a viable solution
because the value of number of days can not be negative and in option
one and two, value of days -3 and -2.5 is negative.
Option
three(4.5, 1.35) can not be correct because library charges fee for a
full day so the number for days would be a whole number. Library would
not charge for 4.5 days, they would either charge of 4 days or 5 days
because 4.5 is not an whole number.
Option four(8, 2.40) is the correct answer because it satisfies our equation;
Y= 0.30 * X
2.40= 0.30 * 8
2.40 = 2.40.
Fourth option (8, 2.40) is the only viable solution to this question.

Answer:
D. StartFraction negative 1 + StartRoot 3 EndRoot Over 2 EndFraction
Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator. Then the denominator is the difference of squares, which will be rational. This simplification is called "rationalizing the denominator."
