Maxine earns $1250 dollars a month. whats is the maximum amount she should use for budget for housing?
jok3333 [9.3K]

Answer:

The National Housing Act of 1937 established guidelines for maximum rents for low-income families.  Originally the maximum rent threshold was set at 20%, however this increased to 30% in 1981 (and has remained at this level ever since).  This figure is used to determine how much of your gross monthly income you should spend on rent.

The 28% Rule is used for determining how much of your gross monthly income should be used for a mortgage, however the FHA's threshold is a little higher at 31% of your gross monthly income on a mortgage.

Renting:

30% of $1,250 = 0.3 × 1250 = $375

Mortgage 28% Rule:

28% of $1,250 = 0.28 × 1250 = $350

Mortgage 31% FHA:

31% of $1,250 = 0.31 × 1250 = $387.50

Therefore, discounting the higher FHA's threshold, the maximum amount to budget for housing is:

  • $375 (if renting)
  • $350 (if buying)

5+ 1/5x=5 what is x
Alenkasestr [34]

Answer:

x = 0

Step-by-step explanation:

Solve for x:

x/5 + 5 = 5

Put each term in x/5 + 5 over the common denominator 5: x/5 + 5 = x/5 + 25/5:

x/5 + 25/5 = 5

x/5 + 25/5 = (x + 25)/5:

(x + 25)/5 = 5

Multiply both sides of (x + 25)/5 = 5 by 5:

(5 (x + 25))/5 = 5×5

(5 (x + 25))/5 = 5/5×(x + 25) = x + 25:

x + 25 = 5×5

5×5 = 25:

x + 25 = 25

Subtract 25 from both sides:

x + (25 - 25) = 25 - 25

25 - 25 = 0:

x = 25 - 25

25 - 25 = 0:

Answer:  x = 0
