The man who can
He can do algebra. He works inside, clean and cool. No sun. No mud. He is a lab technician, and algebra is how he does the job. He drives a nice new truck he paid for himself.
The job
The mix is 1 part concentrate to 4 parts water. The bottle must hold 500 mL. How much concentrate? How much water?
Put it in letters
Concentrate is x. Water is 4 times that.
x + 4x = 500
Solve for x
x and 4x make 5x.
5x = 500
x = 100
The answer
100 mL concentrate. 400 mL water.
100 + 400 is 500. It checks.Why it matters
Mix it wrong and the whole batch is thrown out. A man who guesses wastes time and money. A man who can do the math gets it right the first time, and he goes home clean, in his nice new truck.
Next job: he uses 50 mL a day. 50x = 500. How many days does the bottle last?
Your calculator
He uses a calculator at work. So can you. The Calculator button is at the top of every page.
A calculator is an asset. Use it.
It does the adding and the dividing so you can do the thinking. Check your work with it. Save your time with it.You can too
He did not start out knowing this. He learned it, one step at a time.
People who have the tools to learn can, and will, have better jobs and better pay.
Universal Scope is that tool. It is free. Start with the first problem. You are not behind. You are right on time.
