In the example, multiplying $6 by 25 percent gives a weighted-average CMU of $1.50 for Product A. Step 4. Add the weighted-average CMUs of each product together to give the total weighted-average contribution margin or weighted-average ratio for the company's current product mix.

Saturn's rotation causes it to have the shape of an oblate spheroid; that is, it is flattened at the poles and bulges at its equator. Its equatorial and polar radii differ by almost 10%: 60,268 km versus 54,364 km. Jupiter, Uranus, and Neptune, the other giant planets in the Solar System, are also oblate but to a lesser extent.
