a car decreased in value from $980 to $720 in one year what was the per cent of decrease to the nearest whole per cent ?

kolezko [41]

The decrease was 27%.

Step-by-step explanation:

Old value = $980

New value = $720

Decrease = Old value - New value

$Decrease=980-720=\$260$

Percent decrease = $\frac{Decreased/ amount}{Old value}*100$

$Percent\ decrease=\frac{260}{980}*100\\Percent\ decrease=0.265*100\\Percent\ decrease= 26.5\%$

Rounding off to near whole percent

Percent decrease = 27%

The decrease was 27%.
