A new car is purchased for 20000 dollars. The value of the car depreciates at 12. 5% per year. What will the value of the car be
Georgia [21]

To solve the problem we need to know about depreciation.

<h2>Formula of Depreciation</h2>

The formula of depreciation is given as,

A = P(1-r)^t

where,

A is the value of an object after t years of time,

P is the value of the object at the beginning, and

r is the rate of depreciation.

The value of the car after 11 years is $4,603.81.

<h2>Explanation</h2>

Given to us

  • Cost of Car at the beginning, p = $20,000
  • Rate of depreciation, r = 12.5%
  • Time, t = 11 years

<h3>Value of the car after 11 years</h3>

Substituting the values in the formula of depreciation,

A = P(1-r)^t

Value of the car after 11 years = P(1-r)^n

                                                 = \$20,000(1-0.125)^{11}\\\\&#10;= \$20,000\times 0.23\\\\&#10;= \$4,603.822 \approx \$4,603.81

Hence, the value of the car after 11 years is $4,603.81.

The sum of two numbers is 58. The first number is 8 less than half the second number. Let c represent the first number. Let d re
alexandr1967 [171]

Answer: A ,C,G and H are correct statements. Look into the step by step for more understanding.

Step-by-step explanation:

To solve for this problem let's find the actually numbers.

so we know that c + d=58  and also c= 1/2d-8  

We have two systems of equations

c+d = 58

c= 1/2d - 8  

Solve for c   by substitution.  Substitute the second equation into the first one.

1/2d -8 + d = 58   Add 8 to both sides

1/2 +d = 66

3/2d =66     Divide both sides by 3/2

d=44  Now we  know the d which is the second number is 44  so subtract it from 58 to find the first number.

58 - 44 = 14  

we will represent the statements by letters from A going.

A. The equation c + d = 58 represents the sum of the two numbers

B. The equation c+d=58 represents the sentence "The first number is 8 less than half the second number."

C.The equation c= 1/2d -8 represents the relationship between the two numbers.

D. The equation  c= 1/2d - 8 represents the sum of the two numbers.

E. The number d is 14.

F. The number c  is 44.

G. The number c is 14.

H. The number  d is 44.  

Now looking at the statements, A ,C,G and H are all correct.
