Percent of increase = delta change/total first week x100
delta change = 25- 20 = 5
percent increase = 5/20 x 100 = 100/4 = 25 percent
Let's use the variable "r" to represent the investment rate of the stocks:
2r(500) + r(800) = 45
1000r + 800r = 45
1800r = 45
r = 0.025
2r = 0.05
The $500 is invested at 5%
