Sam bought a stereo that listed for $795. He saved 20% of the original
cost by buying it at a sale and paying cash. How much did he pay for the
stereo?
a. $159
b. $636
c. $63.60
d. $795
First, we need to determine how much Sam saved by getting a 20% discount on the original price:
20% of $795 = 0.20 x $795 = $159
So Sam saved $159 on the stereo.
To find out how much he actually paid, we need to subtract the savings from the original price:
$795 - $159 = $636
Therefore, Sam paid $636 for the stereo. The answer is b.
