The closest amount paid is $23

Step-by-step explanation:

Given

$Price = \$32$

$Mark\ down = 20\%$

Amount = 10% of Marked down price

Required

Determine the amount paid

First, we calculate the marked down price P2:

$P_2 = Price(1 - Mark\ down)$

Substitute values for Price and Mark down

$P_2 = \$32 * (1 - 20\%)$

Express percentage as decimal

$P_2 = \$32 * (1 - 0.20)$

$P_2 = \$32 * (0.80)$

Remove bracket

$P_2 = \$32 * 0.80$

$P_2 = \$25.6$

The payable amount is 10% off the marked down price,

This is calculated as:

$Amount = P_2 - P_2 * 10\%$

Substitute $25.6 for P2

$Amount = \$25.6 - \$25.6* 10\%$

Express percentage as decimal

$Amount = \$25.6 - \$25.6* 0.10$

$Amount = \$25.6 - \$2.56$

$Amount = \$23.04$

The closest amount paid is $23
