At a 5% off sale Alexandra bought a new drill and saved $13. How much did she pay for the drill? (two decimal places)

 

At a 22% off sale Steven bought a new TV for $734. What was the price of the TV before the sale. (two decimal places)

Let the original price of the drill = D

0.95D = D - 13

D - 0.95D = 13

0.05D = 13

D =13/0.05

D = $260 - original price before 5% sale.

$260 - $13 =$247 - What Alexandra paid for the drill.

 

At a 22% off sale Steven bought a new TV for $734. What was the price of the TV before the sale. (two decimal places)

 

Let the original price of the TV = T

T x [100% - 22%] =$734

T x        78%           =$734

0.78T                      =$734

T = $734 /0.78

T = $941.03 - Original price of the TV before 22% sale.
