Three years ago, Ashly bought $920 worth of stock in a software company. Since then the value of her purchase has been increasing at an average rate of 11 12 % per year. How much is the stock worth now?

Step-by-step explanation:

Given data

time if investment= 3 years

amount=$920

rate= 11.12%

we want to find the 11.12% of $920 is

= (11.12/100)*920

=0.1112*920

=102.304

Therefore we are going to add the 102.304 to the amount invested which is

102.304+920

=$1022.304

stock worth is $1022.304

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
