If a man's weekly salary is x and he saves y dollars, what part of his weekly salary does he spend?
He makes $50 and saves $40 so he spends $10. Right? Convert that to x and y and you have it. Don't get confused with x and y. Sometimes it helps to put it in numbers.
To determine the part of the man's weekly salary that he spends, we need to subtract the amount he saves from his total weekly salary and then divide it by his weekly salary.
The amount the man spends can be calculated as follows:
Amount spent = Weekly salary - Amount saved = x - y
To find the part of his weekly salary that he spends, we divide the amount spent by the weekly salary:
Part spent = Amount spent / Weekly salary = (x - y) / x
Therefore, the part of his weekly salary that he spends is (x - y) / x.
To find the part of the weekly salary that the man spends, we need to subtract his savings from his weekly salary and then calculate the ratio between the amount spent and the weekly salary.
Let's denote the part of the weekly salary the man spends as S. We can calculate it using the following formula:
S = (x - y) / x
Here, (x - y) represents the amount the man spends, and x represents his weekly salary.
To calculate the ratio, we divide the amount spent by the weekly salary and express it as a decimal or a percentage.
Let's assume the man's weekly salary is $500 and he saves $100. Substituting these values into the formula, we get:
S = (500 - 100) / 500
S = 400 / 500
S = 0.8
So, the man spends 0.8 or 80% of his weekly salary.
To calculate the specific values for any given weekly salary and savings amount, substitute those values into the formula.
