Let the price of adult's ticket be x
the expression for the child's ticket is x-6

The price of adult's ticket during off-peak season is \frac{1}{2}x
The price of child's ticket during off-peak season is \frac{1}{2}(x-6)

The total cost paid by The Sandlers is $78
The equation is 78= \frac{1}{2}x- \frac{1}{2}(2(x-6)) = \frac{1}{2}x+(x-6)

rearranging to solve the equation
78= \frac{1}{2}x+x-6
78= \frac{3x}{2} -6
78+6= \frac{3x}{2}
(84)(2)=3x
\frac{168}{3} =x
x=56

The price of one adult's ticket is $56 (normal price) and the price of one child's ticket is $50

Order of operation? 5p^2 = h when p =2 and h = 8
Naddika [18.5K]

Given: p=2, h=8

5p^2=h

5(2)^2=8 ------- substitution here

5(4)=8

20 doesn't equal 8

I did exponents first because it comes before multiplication in the order of opertions.
