There are currently two options to complete the goals on time:
1. Build extra ovens over the 3 required
2. Sacrifice sleep to wake up in the middle of the night to bake
Frankly, no one should be taking option 2 given the number of goals and the fact this is a casual game. So I decided to do the math on option 1 - building extra ovens.
If you build extra ovens to complete the goal, you will lose coins on the goal.
I calculated how many coins you would gain or lose if you did the goal as written with 3 ovens each and maxed all recipes.
Based on my analysis, you will gain $14,590 coins per 15 day goal after all recipe servings are sold. The cheapest oven is $35,000 coins, so purchasing one extra oven means you lose ($20,410) coins on the goal. Each extra oven purchased will continue to decrease your profit by the cost of the oven.
This framework is unsustainable.
