$543.20

Step-by-step explanation:

Given : A computer store buys a computer system at a cost of $465.60.

The first selling price   = $776

Markdown percent = 30%

Then, the Current Selling price =  first selling price  - 30% ( first selling price )

= 776 - 0.30 (776) [ We divide percent by 100 to convert it into decimal]

= 776 (1-0.30)   [Distributive property a(b+c)=ab+ac]

=776(0.70) = 776 x 0.70 = $543.20  [To the nearest cent]

Therefore , the current sale price = $543.20
