unknown: :? i need help.
A price is discounted by 15%. Then, the price is discounted by 10%. the combination of these is _______
I Know _______ = 23.5% but have no idea how to explain/ do the problem on my own. HELP!
Let the original price be P.
Then the first discounted price is (1-0.15)*P = 0.85P
The 2nd discounted price is then (1-0.1)*0.85P = 0.765P
The overall discount as a fraction is therefore (P-0.765P)/P = 0.235
Expressed as a percentage this is 23.5%
