Two expressions each represent the sale price of the item are:
Expression B : 0.8p is correct
Expression D: p - 0.2p is correct
<em><u>Solution:</u></em>
The regular price of an item at a store is p dollars
The item is on sale for 20% off the regular price
Therefore,
Regular price = p dollars
Discount = 20 % of regular price
Therefore,
Discount = 20 % of p

Sale price = Regular price - discount price
Sale price = p - 0.2p
Thus Expression D: p - 0.2p is correct
On solving, sale price = p - 0.2p
Sale price = 0.8p
Thus expression B : 0.8p is correct

Here, (a and b) are the base sides of the trapezoid and (h) is the height.
A room is shaped like a trapezoid which has the height of 28 feet and the length of sides as 23 ft and 35 ft. Thus, the area of it is,

Carpet costs $8.30 per square foot. Thus, the cost of carpet with area 812 ft² is,
C=812×$8.30
C=$6739.6
Furniture covers 25% of the floor. Thus, the remaining square feet of carpet are covered by furniture is,

Thus, the area of room is 812 square feet, cost of carpet to cover the room is $6739.6 and the remaining square feet of carpet are covered by furniture is 203 square feet.
