It's definitely a start, but something that is good to know is a loop, and an array. This prevents you from writing out every single possible combination, and makes your code a lot smaller. For example, I made a program that's pretty similar to yours and, and I think it's still pretty readable for a beginner and gets the point across. Here's how it came out:

Code:
#include <iostream>
using namespace std;

const int daysPerWeek = 7;
char* days[] = 
{
		"Sunday",
		"Monday",
		"Tuesday",
		"Wednesday",
		"Thursday",
		"Friday",
		"Saturaday"
};

int main(int argc, char* argv[])
{
	float hours[daysPerWeek];
	float rate[daysPerWeek];
	long int totalEarnings = 0;

	// Get user input in a loop.
	for(int i = 0; i < daysPerWeek; i++)
	{
		cout << "Enter hours worked on " << days[i] << ": ";
		cin >> hours[i];
		cout << "Enter hourly rate for " << days[i] << ": ";
		cin >> rate[i];
	}

	// After they finish, give them some feedback
	for(i = 0; i < daysPerWeek; i++)
	{
		cout << "Your wages for " << days[i] << " are: " << hours[i] * rate[i] << endl;
		totalEarnings += hours[i] * rate[i];
	}

	cout << "Total money earned: " << totalEarnings;
		
	return 0;
}
If you don't understand anything, try looking up at some cplusplus.com tutorials, see if you can find anything similar, and if it really stumps you, youc an come back and ask here. A lot of the concepts I introduced aren't something that will just come to you at once, and will more just build as you make more and more example programs. Edit: Oh Salem getting to it before me....
