Rosalyn is planning to sell her apartment complex. Ten years ago, she bought the eight-room complex for $420,000. The building has gained 2.2% in value every year since she bought it. She charges a monthly rent of $720 for each room, and pays $22,900 per year in upkeep costs. If Rosalyn has kept all of the rooms occupied continuously since she bought it, to the nearest hundred dollars, how much profit will she have made in total when she sells it

answer; is usually (less than) the socially optimal level of consumption;

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"

credit history is used by lenders to determine whether you are a 'risky' person to give their money to.

having a short history provide very little data for the lenders. they wouldn't be able to determine your credit behavior from such a small samples. even if they are perfect.

having long credit history with few blemishes provide larger and more accurate data for the lenders to predict your credit behavior.
