 | Hey. Good morning. I've been looking for you. I would just like to ask something. |  |
|
 | Hey girl, good morning too. What is it? |  |

 | How many pounds of beef worth $2.50 per pound should be placed together with 140 lb worth $3.50 per pound in order to get a beef that can be sold at $3.20 per pound? |  |
|
 | Oh. It's easy. Let's put it this way. Let x be the number of pounds. Then multiply 140 and 3.50 to both sides of the equation. Which is 2.50x + 490 = 3.20x + 448. Solve for x. The answer is 60. Then that's it. |  |

|
 | WOW! You're so good. Thank you very much! |  |
|
 | Sure, no problem. Just try to study Linear Equations. It's very applicable in our life. |  |
