IgorC [24]

Answer:

The value has increased by <u>8 percent</u>.

Step-by-step explanation:

Given:

The value of a house has increased by $4,200 in the past year.

The value last year was $52,500.

Now, to find the percent increased.

<em>Value of house last year increased by = $4200.</em>

So, to get the percent increased:

$\frac{Value\ of\ house\ last\ year\ increased\ by} {Value\ of\ house}\times 100.$

$=\frac{4200}{52500} \times 100$

$=0.08\times 100$

$=8\ percent.$

Therefore, the value has increased by 8 percent.
