a store is having a 20% off sale. the sale price of an item with price p is p – 0.2p. what is an equivalent expression?

The equivalent expression to the sale price of an item is 0.8p, where p is the price of the item.

Solution:

Given that store is having a 20% off sale

The sale price of an item with price p is p – 0.2p

To find: Equivalent expression

Given expression is:

Sale price = p - 0.2p

Where "p" is the price of item

Let us simplify the given expression for sale price to find the equivalent expression

Sale price = p - 0.2p

Factor out p from above expression

Sale price = p( 1 - 0.2)

Sale price = p(0.8)

Thus, sale price = 0.8p

Thus the equivalent expression is 0.8p

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
