Answer: the current value of the house is $343350
Step-by-step explanation:
The initial value of the house on the market was $315,000.
After several years the value increased by 9%. This means that the amount by which the value of the house increased over the years would be
9/100 × 315000 = 0.09 × 315000 = $28350
The current value of the house would be the sum of the previous value of the house and the increase in value. It becomes
315000 + 28350 = $343350
It says the sum, which hints that the two numbers will be added
So we can start the equation with 10+(1/3n)
we are then told they add up to 25
So they will equal 25
So the equation is
10+(1/3n)=25
The answer is 3.618 x 10^10
