In reality, attendance fell by 35 percent from last year. what was this years attendance? im not sure where to begin... am i on the right track if i do... x + 30/100 = 1430 x - 35/100

  to get last year's attendance ... 1.3x = 1430 x = 1430/1.3 = 1100 reality ... this year's was only 65% of last years, (it dropped 35%) so this year's attendance = .65(1100) = 715

  1.3x=1430 x=1430/1.3=1100 so the attendance from last year since it fell by 35% last year only 65% is left so 0.65(1100)= 715 so this years attendance was 715 students
