4:5 8:10 12:15 that some eqivelent ratios
let x be the number of adults
let y be the number of child
3.5 x + 2.25 y = 50
x+ y =20 y = 20 - x
3.5 (20-y ) + 2.25 y = 50
70 - 3.5 y +2.25y =50
70 -1.25 y = 50
y = 16
and x = 4
58 x 64 = 3,712
64 x 50 = 3,200
3,712-3,200= 512
64 x ? = 512
?=8
3,200+512= 3,712
32 Is the answer simple division
