the first screening of the latest movie had a box office take of $1,938. Adults pay 7.50 and children 4.50. there were four time
s as many children as adults. how many tickets sold were children and how many were adult?
1 answer:
7.50a + 4.50c = 1938
c = 4a
7.50a + 4.50(4a) = 1938
7.50a + 18a = 1938
25.5a = 1938
a = 1938/25.5
a = 76
c = 4a
c = 4(76)
c = 304
so there were 76 adult tickets (a) sold and 304 children tickets (c) sold

Step-by-step explanation:
Apply the BEDMAS rule
B=brackets
E=exponents
D=Division
M=multiplication
A=addition
S=subtraction
The circle radius will be 2 1/2
If we multiply the top equation by -4 we can get rid of the x so:
-4x+20y=-12
4x-4y=12
Add these up
16y=0
Y=0
X=3
1.95 = .21(5) + .06m
1.95 = 1.05 + .06m
Solving (if needed)
Subtract 1.05 from each side
1.95 - 1.05 = .06m
.90 = .06m
Divide .06 on both sides
15 = m
