Question

Write an equation to fit the real world situation

Answer 1

Let r be the rate at which the $1500 is invested. Thus r + .005 is the rate at which the $3000 is invested at (be careful on the decimal point)...thus we have
1500r + 3000(r + .005) = 285
Multiply through and get
1500r + 3000r + 15 = 285
Collect and get
4500r + 15 = 285
Subtract 15 and get
4500r = 270
Now divide by 4500 and get
r = .06 = 6%

Thank you. That is what I was thinking.
