Question

Shylah is purchasing 4 patio chairs that are each 25% off the original price p.

Which expressions can she use to find the total cost of all 4 chairs?


Select each correct answer.


0.75p


4(p−0.25p)


3p


4p−0.25p

Answer 1

25% is being taken off the original price, p, of each patio chairs.

That means the price of each patio chair is the full price, p, minus 25% of the original price.

1) To find 25% of the original price, multiply p (original price) by the decimal form of 25%, or 0.25. That means 25% off original price = 0.25p.

2) Now subtract 0.25p from the original price of the chairs to find the price of each (1) chair. p - 0.25p

Shylah is buying 4 chairs at that discounted price. That means you need to multiply the discounted price, p - 0.25p, by 4. Shylah is paying 4(p-0.25p) total for the 4 chairs, which is answer choice B.

Since you can choose more than one choice, you can simplify 4(p-0.25p) by subtracting what is in the parathesis, then multiplying, following the order of operations:

4(p-0.25p)

= 4(0.75p)

= 3p

That is answer choice A.

Answer: Choices A and B, 3p and 4(p−0.25p).

Explanation:

Choices A and B, 3p and 4(p−0.25p).

Answer 2

Answer: Second option is correct.

Explanation:

Let the original price of chair be 'p'.

Number of chairs = 4

Discount rate = 25%

So, Amount of discount would be

`(25)/(100)p\\\\=0.25p`

So, Cost of each chair after discount would be

`p-0.25p`

So, Cost of all 4 chairs would be

`4(p-0.25p)`

Hence, Second option is correct.
