A roast chicken is discounted by 30%, then by 10%.  What is the overall discount?

Let's assume that it ws a valuable chicken, worth $100.00.

 

Discounting this chicken by 30% give us a chicken worth 70% of $100.00   

     --->     0.70 x $100.00  =  $70.00

 

Now we discount the $70.00 by another 10%

     --->     0.90 x $70.00  =  $63.00

 

Our final price of $63.00, when compared to our original price of $100.00:

     --->     $63.00 / $100.00  =  0.63,  or  63%.

 

[The final percentage would be the same no matter what we chose for an original value.]

geno3141, to answer the original question, the total overall discount would be 37%, or $37
