This video teaches "How to solve Formula Problems".
You will be given numbers to replace all letters in the formula EXCEPT one.
Plug all numbers into their places, then solve with algebra to find the only remaining variable.
The video illustrates the procedure using two examples in a very simple manner.
First problem is to convert degree centigrade into Fahrenheit.
Second problem is to find one of the height of a trapezoid.
In the end the tutor instructs to use the exercise sheet to practice Formula Problems and the answer sheet to correct the problems.
