Question 1142345
<br>
I don't know what your six-step method might be....<br>
Let x be the amount invested at 5%; then the amount invested at 12% is 2x+42000.<br>
The interest on the first investment is .05(x); the interest on the second investment is .12(2x+42000).<br>
Write and solve the equation that says the total interest from the two investments was 46800:<br>
{{{.05(x)+.12(2x+42000) = 46800}}}<br>
I leave the calculations to you....
