The original price of a car is entered into spreadsheet cell A1 and the annual depreciation amount in cell B1.

Reil [10]

Answer:

A1 / B1 ;

(D1 - A1) / B1 ;

(A1 - E1*A1) / B1

Step-by-step explanation:

A1 = original price of car

B1 = annual Depreciation amount

Number of years it will take for the car to depreciate totally :

Using the straight line Depreciation relation :

y = mx + c

c = intercept = initial or original value of car

m = annual Depreciation amount

x = number of years

y = value after x years

For total Depreciation, final value, y = 0

0 = mx + c

mx = - c

x = - c / m

Hence, x = A1 / B1

B.)

D1 = car value

Length it will take for car to depreciate to value in D1 :

y = mx + c

y = D1; m = B1 ; c = A1

D1 = B1x + A1

B1x = D1 - A1

x = (D1 - A1) / B1

C.)

E1 = decrease percentage

Time it takes for car to decrease by percentage in E1

y = E1 * A1

E1 * A1 = B1x + A1

(A1 - E1*A1) = B1x

x = (A1 - E1*A1) / B1

Eunice lives in indiana, which has a sales tax of 7%. She just bought a couch whose full price was $1200 but she got 20% off bc

Tcecarenko [31]

Answer:

Total amount paid by Eunice=$1,044

Step-by-step explanation:

Step 1: Determine full price of couch

Full price of couch=$1200

Step 2: Determine tax

Tax=tax rate×full price

where;

tax rate=7%

full price=$1200

replacing;

Tax=(7/100)×1,200=$84

Tax=$84

Step 3: Calculate the sale price

Sale price=Full price-20% discount

where;

Full price=$1,200

discount=(20/100)×1,200=$240

replacing;

Sale price=(1,200-240)=960

Sale price=$960

Step 4: Total amount paid by Eunice

Total amount paid by Eunice=Sale price+tax

where;

Sale price=$960

tax=$84

replacing;

Total amount paid by Eunice=(960+84)=$1,044

Total amount paid by Eunice=$1,044
