The cost of a television was $500. the cost was increased by 10% and then decreased by 10%. what was the final price of the television? plz show the work : )

a. $450
b. $495
c. $500

495

Step-by-step explanation:

500 x .1 = 50

550 x .9 = 495

C, $500

Step-by-step explanation:

the answer would remain the same as its initial value ($500) because if it were to be increased by 10%, which would be 550, and then decreased by that same 10%, it would still end up being $500.

it would look like this:

$500+10%=$550

$550-10%=$500

i hope this helps :)

the line of

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
