Jackson Water Department wants a program that calculates a customer's monthly water bill. The clerk will enter the current and p
revious meter readings. The program should calculate and display the number of gallons of water used and the total charge for the water. The charge for water is $7 per 1,000 gallons. The water company has a mandatory minimum that each customer must pay at least $16.67, even if their bill is lower than the minimum cost. (In other words, every customer must pay at least $16.67).
Required:
Create an IPO chart for the problem, and then desk-check the algorithm twice. For the first desk-check, use 16000 and 13000 as the current and previous meter readings, respectively. For the second desk-check, use 3675 and 1650.

A 260 ft (79.25m) length of size 4 AWG uncoated copper wire operating at a temperature of 75°c has a resistance of 0.0792 ohm.
Explanation:
From the given data the area of size 4 AWG of the code is 21.2 mm², then K is the Resistivity of the material at 75°c is taken as ( 0.0214 ohm mm²/m ).
To find the resistance of 260 ft (79.25 m) of size 4 AWG,
R= K * L/ A
K = 0.0214 ohm mm²/m
L = 79.25 m
A = 21.2 mm²
R = 0.0214 *
= 0.0214 * 3.738
= 0.0792 ohm.
Thus the resistance of uncoated copper wire is 0.0792 ohm
