If Mr Nawa earns N$ x in a week and spend N$ y, what part of his weekly salary did he save?
the amount is x-y
as a fraction of the salary, (x-y)/x
N $x-N $y
15
To find out what part of Mr. Nawa's weekly salary he saved, we need to calculate the savings as a percentage of his earnings.
The formula to calculate the percentage savings is:
Savings percentage = (Savings / Earnings) * 100
In this case, we know that Mr. Nawa earns N$ x in a week and spends N$ y. To calculate his savings, we subtract the amount he spends from his earnings:
Savings = Earnings - Spending
Once we have the savings amount, we can substitute it into the formula to find the savings percentage:
Savings percentage = (Savings / Earnings) * 100
Let's assume Mr. Nawa earns N$ 500 in a week and spends N$ 300.
First, we calculate the savings:
Savings = Earnings - Spending
Savings = N$ 500 - N$ 300
Savings = N$ 200
Next, we substitute the values into the formula to find the savings percentage:
Savings percentage = (Savings / Earnings) * 100
Savings percentage = (N$ 200 / N$ 500) * 100
To simplify the calculation, we divide the numerator (savings) by the denominator (earnings) and then multiply by 100 to get the percentage:
Savings percentage = 0.4 * 100
Savings percentage = 40%
Therefore, Mr. Nawa saved 40% of his weekly salary.
