A used-droid dealership buys a droid for $2900 and then sells it for $4300. What is the percent increase?

Anna71 [15]

The percent increase is 48.28

Step-by-step explanation:

Given,

Purchase price of used-droid = $2900

Selling price of used=droid = $4300

Profit = Selling price - purchase price

Profit = 4300-2900 = $1400

Percent increase = $\frac{Profit}{Purchase\ price}*100$

$Percent\ increase=\frac{1400}{2900}*100\\\\Percent\ increase=\frac{140000}{2900}\\\\Percent\ increase=48.275\%$

Rounding off to nearest hundredth;

Percent increase = 48.28%

The percent increase is 48.28
