Question

a family originally bought a home for $273,830. Now the home’s value is 30% higher than that. What is the value of the home now?

Answer 1

So the home value is 30 percent higher then the original price.

So $273,830

It’s 30 percent higher.
I’m gonna do a short cut here but you can always find 30 percent of the number and add it back to the original value.

Well first 30 percent is 30/100 really since percent is out of a hundred.

We’re increasing 30 percent of the value.
The original value is already 100/100 since thats the full price and original.
We’re adding 30 percent of that so the new value is 130/100 or 130%

This would save a lot of steps and it’s a better way.

So find percentage like what we would do with any other equation.

Since here it’s 130% we multiply the value by 1.3.

Since 130/100 is 1.3 or you can always move the decimal to the left by 2 since it’s divided by a 100.

Now we multiply.

$273,830 * 1.3 = $355,979

Final answer is $355,979

Answer 2

$355,394

100% +30% = 130% = 1.3
