If they give the calorie info for the mix alone (which I thought they were required to do, but I don't have box around here to verify it), just divide the calories in the 3/4 cup yogurt by the number of servings in the mix, then add that to the calories per serving in the mix.
If they only give the calories for the mix "as prepared," you could figure out the calories by:
1. Figuring the total calories in the mix by multiplying the number of servings by the calories per serving.
2. Subtracting the calories in the added ingredients.
3. Adding the calories in 3/4 cup yogurt.
4. Dividing the new total by the number of servings.
For example, Duncan Hines low-fat chewy fudge brownie makes 20 servings @120 calories each, as prepared. This is an aggregate of 2,400 calories. I'm not sure what the added ingredients are but, for the sake of my example, assume you add 1 egg (75 calories) and 1/4 cup oil (480 calories). Subtracting the calories in the added ingredients (555 calories) leaves 1,845 calories in the mix alone. Assume that 3/4 cup yogurt has 90 calories. Adding the yogurt to the brownie mix increases the calories to 1,935. Divided by 20 servings, you end up with about 97 calories per serving.
Another way to figure this is to just subtract the calories in the yogurt from the calories in the added ingredients and divide by 20 servings. 555 calories less 90 calories, divided by 20 = 23 calories, so replacing the added ingredients with 3/4 cup yogurt eliminated 23 calories per serving.
BTW - I can't believe Fitday is saying an egg is 194 calories! That's crazy--according to all the sources I rely on for calorie data (calorieking, calorie-counters, Bally's online, the egg carton itself), one large egg is 70 to 80 calories. Even a jumbo egg is only around 95 calories.
