Question

Consider a gas and electric bill that
sets two levels of use as follows:
Gas Electric
Baseline Quantities 31 therms 238.7 kwh
Baseline price $.504 /therm $.094 /kwh
Over Baseline Price $.824 /therm $.133 /kwh
Write a program that takes starting and ending
readings for gas and electric meters and calculates
charges to the nearest cent. Use one function to
calculate charges for both gas and electric so as to
eliminate duplicate calculations.
I really do not understand what this is asking i dont need the code i just need an explaination.

Answer 1

this is what i have so far

#include<iostream>
double price( double amt, double baselineAmt, double baselinePrice, double oberBaseLinePrice);
using namespace std;
int main()
{
int gas, costofGas, amtGas;
cout<<"enter the price for the gas"<<endl;
cin>>gas;
costofGas=price(amtGas, 31, .504, .824)
cout<<price;
return 0;
}

Answer 2

Actually, the problem gives you the cost for both gas and electric. You need to determine the therms/kwhs used (by subtracting start value from end value for each. Basically you just make these up), then create a functions that can calculate the total price for either gas or electric from these values. In pseudo-code it might look like this:

Get starting gas value
Get ending gas value
Get starting electric value
Get ending electric value
Compute gas charges
Compute electric charges

Your compute function might look something like this:

ComputePrice(bool isElectric, startvalue, endvalue)
If isElectric false // we're dealing with gas charges then
therm = (end-start)
overtherm = therm - 31
Price = therm * .504 + overtherm * 824
return the price

You'll need to complete the Else part of the first if statement (isElectric) to handle the electric charges. This should at least get you started.

Answer 3

i'm using this in c++ so it would be the same thing basically right

Answer 4

Yes, what I showed you here is pseudo-code. It can be implemented in any language. You just need to use the right syntax; such as cout>> for C++.
