A computer store buys a computer system at a cost of ​$465.60. The selling price was first at $ 776​, but then the store advertised a 30 % markdown on the system. Answer parts a and b.The sale price is

a) To find the sale price after a 30% markdown, we first need to calculate the amount of the markdown.

Markdown = 30% of $776 = 0.30 x $776 = $232.80

Sale Price = Original Price - Markdown
Sale Price = $776 - $232.80
Sale Price = $543.20

Therefore, the sale price after a 30% markdown is $543.20.

b) To calculate the profit the store made on selling the computer system, we need to subtract the cost price from the sale price.

Profit = Sale Price - Cost Price
Profit = $543.20 - $465.60
Profit = $77.60

Therefore, the profit the store made on selling the computer system is $77.60.
