A used-droid dealership buys a droid for $2900 and then sells it for $3900. What is the percent increase?

rewona [7]

Answer:

The percent increase is 34.48276%

Step-by-step explanation:

we are given

original price =$2900

new price =$3900

now, we can find change in price

change in price = (new price)-(original price)

change in price =3900-2900

change in price =1000

percent increase = (change in price)/(original price) *100

percent increase is

$=\frac{1000}{2900}\times 100$

$=34.48276$
