+103 20 pupils went out for a show in the theater. the price of a ticket in the hall costs 30$ and a ticket at the stadium costs 60$. over all the pupils paid 750$. how many pupils sat in the hall and how many at the stadium?
+129849 Let's call the number that went to the hall "x".....then the number that went to the stadium is just "20-x"
And the number that went to the hall times the price of a hall ticket plus the number who went to the stadium times the price of a stagium tickest = $750. Mathematically, we have...
(x)(30) + (20-x)(60) = 750 simplify this.......
30x + 1200 - 60x = 750
-30x = -450 divide both sides by -30
x = 15 and this is the number who went to the hall
And (20-x) = (20-15) = 5......and that's the number who went to the stadium
