One thing to remember about percent is that "%" means the same as "/100".

A) 25% = 25/100

B) (25/100)*(total pieces) = 20 pieces
Multiply by 100/25 = 4
.. total pieces = 4*(20 pieces) = 80 pieces

Answer: 80 pieces of paper

Yu Xing paid 3.60 dollar for 2 pens after a 10 percent discount .What was the usual price of 1 pen.
notka56 [123]

Answer:

2 $

Step-by-step explanation:

let the original price be x

price after 10% discount = 3.60$

x -  \frac{10}{100} \times x = 3.60

\frac{100x - 10x}{100}  = 3.60 \\  \frac{90x}{100}  = 3.60 \\ 9x = 36 \\ x = 4

The original price of 2 pens is 4$

original price of one pen = 4/ 2

<u>= 2 $</u>

Alicia is buying 6 oranges that cost $1 per kilogram is it reasonable to say that the cost of the oranges will be greater than $
34kurt

Answer: Yes

Step-by-step explanation:

I am not sure if this is correct, but a kilogram is a very small unit of measure. I would assume that it is greater since 1000kg is equal to 1g. The oranges would have to weigh almost nothing for it to be less than $6.
