<br>
Here is a quick and easy alternative to the standard algebraic method for solving "mixture" problems like this.<br>
(1) Determine, by whatever simple calculations you choose, that 43% is 6/15 = 2/5 of the way from 37% to 52%.<br>
(2) That means 2/5 of the mixture has to be the 52% aluminum.<br>
