Question 1176115: Josh invested a total of $5000 in 2 bank stocks(TD and RB) TD bank stock increased in value by 6% and the RB increased by 7% over one year. After one year Josh investments had increased in value by $230. What was his original investment in each bank stock? Create a linear system to represent this problem.
Solve the 2X2 linear system to obtain the original amounts invested. Given the simplicity of the first equation, my choice would be the Substitution method. Find an expression for RB in terms of TD.
