Alex

The decrease is 8.7%

Step-by-step explanation:

Old price = $23000

New price = $21000

Difference = New price - Old price

Difference = 21000 - 23000 = -2000

The negative sign indicates the decrease.

$Percent\ decrease=\frac{Difference}{New\ value}*100\\\\Percent\ decrease=\frac{2000}{23000}*100\\\\Percent\ decrease=\frac{200000}{23000}\\\\Percent\ decrease=8.69\%$

Rounding off to nearest tenth;

Percent decrease = 8.7%

The decrease is 8.7%
