Discount sale

After a discount, a computer costs 9,600 CZK. What was the original price if the shop reduced it:
a) by half?
b) by a third?
c) first by one-fifth and then by 160 CZK?

Final Answer:

a =  19200
b =  14400
c =  12200

Step-by-step explanation:


a-a/2 = 9600

a = 19200


a = 19200/1 = 19200

a = 19200

Our simple equation calculator calculates it.

b-b/3 = 9600

2b = 28800


b = 28800/2 = 14400

b = 14400

Our simple equation calculator calculates it.

c-c/5 - 160 = 9600

4c = 48800


c = 48800/4 = 12200

c = 12200

Our simple equation calculator calculates it.
