8. John buys a TV for $1900. He later sells it for
$750. Calculate his percentage loss, correct to
one decimal place.

John bought the TV for . . . . $1,900

John sold the TV for . . . . . $750

John lost this much on the TV . . . (1,900 - 750) = $1,150

What fraction of the amount he paid did he lose ?

$1,150 / $1,900 = 0.6053 of the amount he paid never came back

What is this fraction as a percentage ?

0.6053 = 60.53 %

Rounded to one decimal place:  60.5 %  

John took a beating on that TV.  I hope he got a lot of good use out of it while he had it.

60.5% loss

Step-by-step explanation:

Loss = Cost Price – Selling Price =$1900-$750= $1150

% loss= Total loss/Cost price ×100

=1150/1900×100

=60.5%

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
