Question

Natalie has $250 in savings. At the end of 6 months, she has $450 in savings. What is the percent increase in the amount of her savings?

Answer 1

Answer: 80%

Explanation:

Rule of 3.

Let's put the money on the left side and the percents on the right side.

`(250)/(450)=(100)/(x)`

Solve for x:

`x=(450*100)/(250)`

`x=180`

Subtract 100 from 180

180-100=80

Answer 2

80 percent. 80 percent of 250 is 200 and 250 increased by a total of 200 therefore 80%
