Answer is 32 books
So i am not sure if the answer listed there are correct
But this is the way you solve it
x=number of books
change 64% percent to a decimal, 0.64
Put everyhting into equation
0.64×50=x, then solve
x=32
64% of 50 books is 32 books
Step-by-step explanation:
Let adults = a and children = c,
(1) a + c = 1100
(2) 48a + 23c = 45300
From the (1) equation, a = 1100 - c
Then substitute a = 1100 - c into (2),
48(1100 - c) + 23c = 45300
52800 - 48c +23c = 45300
-25c = -7500
c = 300
Substitute c = 1500 into a = 1100 - c,
a = 1100 - 300
a = 800
Therefore, 800 adults and 300 children bought the tickets
