During a sale, a store offered a 15% discount on a stereo system that originally sold for $880. After the sale, the discounted price of the stereo system was marked up by 15%. What was the price of the stereo system after the markup? Round to the nearest cent.

The price of the stereo system would be $860.20

$860.20

Step-by-step explanation:

When the stereo was discounted by 15%, the resulting price was $748. Then the stereo price was increased by 15%, which brought the price up to $860.20.

Original price discounted:

$880 • 0.15 = $132

$880 – $132 = $748

Discounted price marked up:

$748 • 0.15 = $112.20

$748 + 112.20 = $860.20

I hope this helps.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
