Question 53066
In one year, Cholena Youngblood earned the same amount of interest from an investment at 8% annual interest as an investment at 12% percent annual interest. She had invested $1500 more at 8%.How much money did she invest at 12%.
:
Let x = amt invested 12%
:
Then [x+1500] = amt invested at 8%
:
 The problems states: 
8% int = 12% int
:
.12* x = .08*(x + 1500)
:
.12x = .08x + 120
:
.12x - .08x = 120
:
.04x = 120
:
 x = 120/.04
:
 x = $3000 invested at 12%
:
amt invested at 8%: 3000 + 1500 = $4500
:
:
Check:  .12(3000) = .08(4500)
