Respuesta :

Look at the answers and be logical, try rounding up so instead of 45% try 50% now 22.5 would be half the number, have a look at the answers and see what is closest to double 22.5. C looks reasonable. Hope I helped, have a nice day :)
C. Is The Answer You’re Looking For.

Half Of 50 Is 25, And 22.5 Is Close To 25. So, The Answer Must Be C.
