The formula, pe gives the relationship between resistance (R), voltage (1) and power P). Solve the formula for resistance.

If you would like to know how many points did Nelson score, you can calculate this using the following steps:

Craig: 12 points
Nelson: n points = ?
Marla: twice as many points as Craig ... 2 * 12 points = 24 points
           5 fewer points than Nelson ... n - 5

n - 5 = 24
n = 24 + 5
n = 29 points

The correct result would be 29 points.
