Question

in a certain shop , items were put in a showcase and assigned prices for january. Each month after that, the price was 10 precent less then price for the previous month. If the price of an was p dollar for january, what is the price for april?

Answer 1

Answer:

$ 0.729 p

Explanation:

January price of the Item = $ p, 10% of p = $ 0.1 p

February price of the item = $ p - $0.1 p = $ 0.9 p

10% of $ 0.9 p = $ 0.09 p

March price of the item = $ 0.9 p  -  $ 0.09 p = $ 0.81 p

10% of $ 0.81 p = $ 0.081 p

April price of the item = $ 0.81 p - $ 0.081 p = $ 0.729 p
