The DVD player has a list price of $210. It is marked down 30%. This makes its price $210 ( 1 - 30%)

=> $210( 1 - .3)

=> $210 * 0.7

John gets another 20% employee discount. So the price for him is

$210 * 0.7 * (1 - 20%)

=> $210 * 0.7 * (1 - .2)

=> $210 * 0.7 * 0.8

=> $117.6

**Therefore John pays $117.6**

Given that the original price of the DVD player is $210.

First we need to calculate the cost of the DVD player after the 30% off.

==> The sale price = original price - discount

==> Sale price = 210 - (30/100 * 210)

= 210 - 63 = 147

Then, the sale price = $147

Now we will calculate the employee discount which is 20% off the sale price.

==> Employee price = sale price - 20% discount

==> employee price = 147 - (20/100 * 147)

= 147 - 29.4 = 117.6

**Then John pays $117.6**
