it is not the case that if electric rates go up, then usage will go down nor is it true that either new power plants will be built or bulls will not be late. therefore, usage will not go down and bills will be late.

P - new power plants will be built

B - Bills will not be late

R does not imply U, P or B do not imply ~R
