Swifty Corp. enters into a contract with a customer to build an apartment building for $$995,600.$ The customer hopes to rent apartments at the beginning of the school year and provides a performance bonus of $$145,500$ to be paid if the building is ready for rental beginning August $1,2021.$ The bonus is reduced by $$48,500$ each week that completion is delayed. Swifty commonly includes these completion bonuses in its contracts and, based on prior experience, estimates the following completion outcomes:
