Sagot :
Answer:
C. $56
Step-by-step explanation:
We have been given that a DVD player with a list price of $100 is marked down 30%.
Let us find the price of DVD player after marked down by figuring out 70% (100-30) of $100.
[tex]\text{Price of DVD player after marking down}=\frac{70}{100}\times \$100[/tex]
[tex]\text{Price of DVD player after marking down}=\$70[/tex]
Therefore, the price of DVD player after marking down by 30% will be $70.
As John gets an employee discount of 20% off the sale price, so to find the amount paid by John we need to figure out 80% (100%-20%) of $70.
[tex]\text{The amount paid by John for DVD player}=\frac{80}{100}\times \$70[/tex]
[tex]\text{The amount paid by John for DVD player}=8\times \$7[/tex]
[tex]\text{The amount paid by John for DVD player}=\$56[/tex]
Therefore, John paid $56 for the DVD player and option C is the correct choice.
