A pаtient is tо be treаted using а three-field prоne pelvis SAD plan. The lateral fields use wedges. Hоw many MUs will each lateral field receive if the prescribed dose is 180 cGy per fraction, the fields are equally weighted, have a wedge factor of 0.74, output of 0.90 cGy/MU, and TMR of 0.812?

The risk-free rate is 4%. You want to build a cashless buffer with a $10-buffer (that is, you short multiple calls with a strike price $10 above the spot price). You can short any number of calls, including fractions of calls. How many calls should you short? Enter your answers as a number of calls rounded to the nearest 0.001. For example, for 12.3456 calls, enter 12.346.
