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

D. y = 0.75<em>x</em> + 11

We can prove this by substituting <em>x</em> with 1 (the initial measurement)

y = 0.75(1) + 11 = 11.75
