A computer is on sale for Rs 1,600, which is a 20% discount off the regular price
What is the regular price?

y x 0.8 = 80% of y, so do it in reverse. In this case, y = 1600, so 1600/0.8 = 2000

Edit: Keep in mind 1600 is 80% of Regular Price

Rs. 1920

Step-by-step explanation:

Rs 1600: 20% discounted price

1600+ [ (20÷100) x 1600]

1600+ 320

= Rs. 1920 (Regular price)

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
