5n + 3n = 1790 n= tickets sold for non student 2n-100 = tickets sold for student So, 5n + 3(2n-100)= 1790 5n + 6n - 300 = 1790 11n = 1790+300 11n= 2090 n= 190 So, substituting the value of n we 5(190)+ 3(2(190)-100) =1790 950 + 840 =1790
.05(100)+.15(93)+.60(80)+.20(81)= 84.35 Marissa's grade is 84.35%
