Question 3,4&5 Cindy bought a car for $21,330. A few years later she sold the car for $19,700.find the percent of change in

san4es73 [151]

The change in value was 8% which amounts to $1630

Further explanation:

The change in value is calculated by using the initial price and selling price of the car.

Given

Purchase Price = P = $21330

Selling Price = S = $19700

As the selling price is less than the purchase price, Cindy had loss.

$Loss=L= Cost\ price-selling\ price\\=21330-19700\\=\$1630$

Percentage of loss will be calculated as:

$Percent\ loss=\frac{1630}{21330}*100\\=8\%$

The change in value was 8% which amounts to $1630

How are the solutions to the following two equations related m+5=72 m+72=5

EastWind [94]

To see how they are related, let us solve the two equations.

FIRST EQUATION

$m + 5 = 72$

$\rightarrow \: m = 72 - 5$

$\rightarrow \: m = 67$

SECOND EQUATION

$m + 72 = 5$

$\rightarrow \: m = 5 - 72$

$\rightarrow \: m = - 67$

Hence the solutions to the two equations are ADDITIVE INVERSE of each other.
