The scale is the ratio of the model to the real thing. So, in the scale 1:50, the model is 1, while the real thing is 50. Now, just make a proportion: the model : the real thing = the model dimension : the real thing dimension 1 : 50 = x : 8m
From here: x = 8m * 1 / 50 = 0.16 m = 0.16 * 100 cm = 16 cm.
The answer is 210 children tickets were sold . if you multiply the first equation by 7 it would be 7x+7y=2590. then subtract equation 2 from 1 you will have 4x=840 so x=210. Also you can use substitution method.
