# Question 5c91e

May 24, 2017

#### Explanation:

As it's stated an increase is the plus to the original condition. Therefore in this case is 100% (original price) + 325% (the increase).

You can see it form the following formula

% = ((X_1 - X_0) / X_0)100 

Where ${X}_{1}$ is the actual value and ${X}_{0}$ is the original value

Then if we solve for ${X}_{1}$ we could have

X_1 = (X_0 xx %)/100 + X_0#

Replacing values:

${X}_{1} = \frac{3000 \times 325}{100} + 3000$

${X}_{1} = 12750$

Or as I say in the answer

${X}_{1} = 3000 \times \frac{425}{100} = 12750$

Now you just need to add the tax, just joking...

Hope this helps
