because of celebration of holiday, one shop decides to put all items in store 90 percent discount, the question is : how much was the price for a now 59 RMB item?
my maths teacher's answer is: 59x(1+10%) = 59x1.1 =64.9 RMB.
my answer is : 59/(1-10%) = 59÷0.9 = 65.6 RMB
Can anyone tell me please: who is right,my maths teacher or I?
--------------------------------------------------------
i think you are right.
assume the original price is x RMB
then the equation would be like this:
x*0.9 = 59
so, x = 59/0.9.
