Question 1200511
<br>
The response from the other tutor shows a typical setup for solving the problem using formal algebra.  Assuming you are studying algebra, you should understand that method.<br>
If formal algebra is not required and you want a fast path to the answer, you can do the following.<br>
46% is 6/10 = 3/5 of the way from 40% to 50%.
That means 3/5 of the mixture should be the higher percentage antifreeze.<br>
ANSWERS: 3/5 of 50 gallons, of 30 gallons, of the 50% antifreeze, the other 20 gallons of 40%<br>
CHECK:
.50(30)+.40(20) = 15+8 = 23
.46(50) = 23<br>
