IgorC [24]

Answer:

The value has increased by 8 percent.

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.

Value of house = $52,500.

Value of house last year increased by = $4200.

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.

nalin [4]

Let s be the son's age 15 yeasr ago and m the mother's age that year.

$s = \dfrac{m}{3}$

We also know that:

$m = s+30$

Plotting vallues:

$s = \dfrac{m}{3}\\\\\\3s = s+30\\\\2s = 30\\\\s = 15\\\\m = 45$

Remember that they were that age 15 years ago.

So their actual age is 30 and 60.
