13. make sense and persevere a computer store buys a computer system at a cost of $485.60. the selling price was first at $776, but then the store advertised a 30% markdown on the system. a. find the current sale price. round to the nearest cent if necessary.

Answer

Explanation:

Step1: Calculate the markdown amount

The markdown is 30% of the original selling - price of $775. The formula for the markdown amount $M$ is $M = 0.30\times775$. $M=0.30\times775 = 232.5$

Step2: Calculate the current sale price

The current sale price $P$ is the original selling - price minus the markdown amount. The formula is $P=775 - M$. $P = 775-232.5=542.5$

Answer:

$542.50$
