A $129.50 stereo is discounted 40%. The next month, the sale price is discounted 60%. Is the stereo now “free”? If not, what is the sale price?
Accepted Solution
A:
--------------------------------------------------------------------------- Original Price --------------------------------------------------------------------------- $129.50
--------------------------------------------------------------------------- Discount --------------------------------------------------------------------------- 40% of $129.50 = 0.4 x 129.50 $51.80
--------------------------------------------------------------------------- Price after discount --------------------------------------------------------------------------- $129.50 - $51.80 = $77.70
--------------------------------------------------------------------------- Further discount of 60% -------------------------------------------------------------------------- 60% of $77.70 = 0.6 x 77.7 = $46.62
--------------------------------------------------------------------------- Price after discount --------------------------------------------------------------------------- $77.70 - $46.62 = $31.08
--------------------------------------------------------------------------- Answer: It is not free. It still cost $31.08. ---------------------------------------------------------------------------
