Question

A laptop computer originally priced at $1,600 now sells for $1,800. What is the percent of increase?

Answer 1

12.5%

Step-by-step explanation:

The percent of increase can be calculated as:

`(v_f-v_i)/(v_i)*100`

Where vf is the final value and vi is the initial value.

So, replacing vf by $1800 and vi by 1600, we get:

`(1800-1600)/(1600)*100=(200)/(1600)*100=12.5\text{ \%}`

Therefore, the percent of the increase is 12.5%
