minimum = 19
maximum = 46
Q1 =(26 + 28)/2 = 54/2 = 27
Q2 (median) = (30 + 31)/2 = 61/2 = 30.5
Q3 = (38 + 40)/2 = 78/2 = 39
range = max - min = 46 - 19 = 27
Interquartile Range (IQR) = Q3 - Q1 = 39 - 27 = 12

Hence the equation is
.
Val has rented the bicycle for 8 days.
Step-by-step explanation:
Given,
The total cost for rent a bicycle = $123
Fixed rental fee = $55
Charge of 1 day = $8.50
Solution,
Let the total number of days Val rented the bicycle be 'x'.
The total cost for rent a bicycle is the sum of fixed rental fee and charge of 1 day multiplied with total number of days.
Now framing the above sentence in equation form, we get;
The total cost for rent a bicycle = Fixed rental fee + Charge of 1 day × total number of days
On putting the given values, we get;
So the equation can be written as;
Now we solve the expression for calculating total number of days, we get;
Hence the equation is
.
Thus Val has rented the bicycle for 8 days.
