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
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 :)
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 \(15\%\)
