I need help again lol <3 A music store buys instruments and then sells them for 30% more than they paid.
During a 20% off sale, the store offers a clarinet for $93.60.

How much did the store pay for the clarinet?

$93.60 x 0.2 = $18.72

$93.60 + $18.72 = $112.32 = Price before 20% discount.

$112.32 ÷ 100 x 30 = $33. 696 = Discount of 30%

$112.32 - $33.696 = $78.624 = Original Price

Therefore, the store paid $78.624 for the clarinet before the 30% markup and 20% discount.

It's just a process of working backwards.

Hope this helps :))

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
