Question

Setting up the math for a two-step quantitative problem?

Answer 1

To solve a two-step quantitative problem in math, you should follow these steps: determine the system of interest, identify the known and unknown quantities, substitute the known quantities into the appropriate equation, obtain the numerical solution, and check if the answer makes sense.

Step-by-step explanation:

1. Step 1. Determine the system of interest and identify what information is given and what quantity is to be calculated. A sketch will help.
2. Step 2. Make a list of what quantities are given or can be inferred from the problem as stated (identify the known quantities).
3. Step 3. Identify exactly what needs to be determined in the problem (identify the unknown quantities). A written list is useful.
4. Step 7. Substitute the known quantities, along with their units, into the appropriate equation and obtain numerical solutions complete with units.
5. Step 8. Check the answer to see if it is reasonable: Does it make sense?
