Question

A store marks down the price of a necklace from $389.85 to $314.15. By what percent did the price decrease? Round to two decimal places.

a. 13.21%

b. 15.75%

c. 19.42%

d. 24.10%

Answer 1

Answer: C. 19.42 %

Explanation:

Since, the initial price of the necklace = $ 389.85,

Final price of the necklace = $ 314.15,

Total discount in the price = 389.85 - 314.15 = $ 75.7

Since,

`\text{ The discount percentage}=\frac{\text{ Total discount}}{\text{Initial price}}* 100`

`=(75.7)/(389.85)* 100`

`=(7570)/(389.85)=19.4177248\approx 19.42\%`

Hence, The price decreased 19.42%.

⇒ Option C is correct.

Answer 2

c. 19.42% because you subtract 389.85 from 314.15 which equals 75.7. So then set it up like an algebraic equation. 389.85x=75.7 divide 75.7 by 389.85 to find the decimal. Then you have to move the decimal to the right two places, since it is a percentage. And then round your answer, so c. 19.42% is your answer. Hope this helped! :)
