Question

!!
HELP Neal invests in a technology company. He buys the stock at $121.16 and sells it at $152.00. Find the percent of increase. Round your answer to the nearest whole percent.

Answer 1

So this can be solved as a ratio and the form I use for ratios is

Is. =%
Of. 100
What we're looking for is a precentage
152. = x
121.16. 100
Cross multiply
121.16x=15200
Divide both sides by 121.16
X=125.4539
About 125%
-100% of the original amount
So the percentage of increase is about 25%
