Answer: The required expression would be
.
Step-by-step explanation:
Since we have given that
Let the regular price of an item be 'p' dollars.
Discount % = 20%
So, Amount of discount would be

So, the expression represents the sale price would be

.
Answer:
<u>Part A: Cost for the flooring is $ 4,231.50</u>
<u>Part B: Cost for the flooring is $ 5,531.50</u>
Step-by-step explanation:
Step 1:
Let's calculate the area of the living/dining room, this way:
Area = 26 * 25
Area = 650 ft²
Step 2:
Let's calculate the cost of the flooring if Nancy installs it:
Cost = $ 6.51 * Area of the living/dining room
Cost = 6.51 * 650
<u>Cost = $ 4,231.50</u>
Step 3:
Let's calculate the cost of the flooring if the flooring company installs it:
Cost = $ 8.51 * Area of the living/dining room
Cost = 8.51 * 650
<u>Cost = $ 5,531.50</u>
Since there are 22 participants all in all. The possible combinations of the two picked for practice first is,
22C2 = 231
The probability of picking one from each gender will be solved through the calculation below.
(10C1)x(12C1) / 231 = 40/77
In percentage, the answer would be approximately 52%. Thus, the answer is the first choice.
