Question 1162586
<br>
You should understand how to solve this kind of problem by the standard algebraic method, as shown by the other tutor.<br>
However, if a formal algebraic solution is not required, look how easy it is to solve this problem:<br>
$1.20 is 2/3 of the way from $1.00 to $1.30.
Therefore, 2/3 of the mixture is the tea worth $1.30 per pound.<br>
ANSWER: 2/3 of the 12 pounds, or 8 pounds, is the tea worth $1.30 per pound; the other 4 pounds is the tea worth $1.00 per pound.<br>
CHECK:
8(1.30)+4(1.00) = 10.40+4.00 = 14.40
12(1.20) = 14.40<br>
You can use that method to solve ANY two-part mixture problem....<br>
