So what is a quadrilateral something that has four sides. So as long as the sides DON't intersect they're fine but. A rhombus is parallel the sides won't cross. Trust me, this is a rush job. a trapezoid has only ONE parallel side but is it still parallel? It's the last option.<span />
End of First Year (750/100)x12(3/5)=54 $750+54=804 End of Second Year (804/100)x12(3/5) = 58 $804+58=862 End Of Third Year (862/100)x12(3/5) = 62 $862+62=924
