Final answer:
To determine the minimum amount of realized income per month to keep your housing expense in the acceptable range, set up a proportion using 30% of the mortgage payment and solve for x.
Step-by-step explanation:
To determine the minimum amount of realized income per month to keep your housing expense in the acceptable range, we can use a proportion. Let's assume that the acceptable range for housing expense is 30% of your income.
First, we need to find the total monthly income that corresponds to 30% of the mortgage payment. We can set up a proportion:
x/1248.90 = 30/100
Cross-multiplying, we get:
100x = 30 * 1248.90
Simplifying, we find:
x = (30 * 1248.90)/100 = $374.67
Therefore, the minimum amount you must have in realized income per month to keep your housing expense in the acceptable range is $374.67.
