Question

The price of an item increased by 25%. If the price of the item after the increase is $2, find the original price.

a) $1.50, b) $1.60, c) $1.75, d) $2.50, e) $3.20

Answer 1

`x+0.25x=2\\ 1.25x=2\\ x=\$1.6\Rightarrow B`

Answer 2

25 % = 25/100 = 0.25

x ⇒ original price


`x + 0.25x = 2 \\ 1.25x = 2 \\ x = 2/1.25 \\ x = 1.6`

The original price was $1.6
