Question

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

Answer 1

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

= 2 $
