Problema Solution
Suppose 38lbs of coffee beans are required to produce 2lbs of coffee. How many lbs of coffee beans are required to produce 318lbs of coffee beans?
Answer provided by our tutors
Set up the problem like this:
38 lbs coffee beans/2lbs coffee = ? lbs coffee beans/318lbs of coffee
Where ? is the amount you wish to solve for.
Now you want to isolate the ?, so multiply both sides by 318lbs. You get:
38lbs/2lbs * 318lbs = ?/318lbs * 318lbs
38lbs/2lbs *318lbs = ?
Which you can now figure out on your calculator.
