If the original pair of a pair of shoes is $80 but a sign above the shoes reads “ sale - 20% discount”, then what price would a customer pay for the shoes (excluding tax)?
a. 64
b. 80
c. 60
d. 16
e. 6

A. 64

Step-by-step explanation:

The shoes are 80 dollars.  We get a 20% discount

Discount = 80*20%

                = 80*.20

                  =16

The sales price = original price less the discount

                          = 80 -16

                           = 64

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!
