Answer 2

Given

monkey chunks cereal is normally $3.25 per box but today it's on sale for 25% off.

Find out  the new price.

To proof

As given

monkey chunks cereal is normally per box = $3.25

it's on sale for 25% off.

25% written in the decimal form

$= \frac{25}{100}$

= 0.25

25% off in the price = 0.25 × 3.25

                                = 0.8125

new price = $3.25 - $0.8125

                = $2.44 (approx)

correct option is (b) i.e  $2.44.

Hence proved
