A lender estimates the closing costs on a home loan will be 3.75% of the loan amount of $120,000. the actual closing costs are l
Furkat [3]

The lender’s good faith estimate is that he made a poor estimate; it was off by more than 0.5% of the actual closing costs.

<h3>What is closing cost?</h3>

All the expenduture and charges charged by a lander and other parties is called the closing cost.

A lender estimates the closing costs on a home loan will be 3.75% of the loan amount of $120,000.  Thus, the estimate closing cost is,

C_{ec}=\dfrac{3.75}{100}\times120000\\C_{ec}=4500

The actual closing costs are listed below.  

  • Loan origination   $300
  • Title insurance      $600
  • Attorney’s fees     $1,250
  • Appraisal               $550
  • Inspection             $525
  • Recording fees     $125
  • Escrow                  $2,000.

The total annual cost is,

C= $300 +$600 +$1,250 +$550 +$525 +$125 +$2,000\\C=4800

Total annual cost is $300 more than the estimate closing cost. In the percentage form,

p=\dfrac{4800-4500}{4500}\times100\\p=6.66\%

Thus, the lender’s good faith estimate is that he made a poor estimate; it was off by more than 0.5% of the actual closing costs.

Aye help me please :)
mina [271]

Answer:

there's no solution.

Step-by-step explanation:

if y = 3x -4 then use this instead of y in the second equation

9x -3(3x+4) = 14 ➡9x-9x -12 = 14 9x will eliminate -9x and -12 can't be = 14 so there's no solution
