¿necesito ayuda con problemas de matemática?

100 baterias a un costo total de "q" quetzales --> cada batería costó q/100 quetzales. Vende cada bateria a 50% arriba del costo original --> 100%+50% = 150% --> factor 1.5 Multiplicando: q/100 por 1.5 = 1.5/100 q = 0.015q quetzales precio de venta de cada batería.

X=precio de venta de cada bateria y=costo original de cada bateria 100y=q 100x=q+0,50q 100x=1,50q x=0,02q***RTA.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
