Question

You invested $2,300 in a stock. your account now has a value of $2,643. your percentage gain on the investment (rounded to the nearest percent) was

Answer 1

we know that

the amount $\ 2,300$ -------> represent the $100\%$

so

Find the percentage of the amount $\ 2,643$

by proportion

$\frac{100}{2,300} =\frac{x}{2,643} \\\\ 100*2,643 =x*2,300\\\\ x =\frac{100*2,643}{2,300} \\\\ x= 114.91\%$

Find the percentage gain

$Percentage\ gain =114.91-100 =14.91\% =15\%$

therefore

the answer is

The percentage gain on the investment is $15\%$

Answer 2

2,643 - 2,300=343
343 divide 2,300= 0.1491304348
When rounded to the nearest percent
15%
Just remember that when finding percent change subtract the bigger no. From the smaller no. Then divide the answer by the original amount.


I hope this helps you :)
