Question 1127025
<br>
Oh, brother!!!!<br>
It is NOT "against the rules of this forum" to respond to a message if it is clear what the question is.<br>
The other tutor's response is appropriate, and correct.<br>
Here is a way that will get you to the answer to a question like this much faster and with much less work than the standard algebraic method used by the other tutor.<br>
(1) The $5.25 cost per pound is 3/5 of the way from the $4.50 per pound cost of the TF seed to the $5.75 per pound cost of the KB seed.<br>
(Do some simple arithmetic: 5.25 - 4.50 = .75; 5.75-4.50 = 1.25; .75/1.25 = 3/5)<br>
(2) That means 3/5 of the mixture needs to be the higher priced KB seed.<br>
Therefore, to make 5 pounds of the mixture, you need 3 pounds of the KB seed and 2 pounds of the TF seed.
