We use the equation to solve for x:
78 = 0.5x + (x - 6)
78 = 1.5x - 6
1.5x = 84
x = 56
But 56 is the regular price of an adult, so subtract 6 to get $50, the regular price of a child. The answer is (A).
The equation is close! But it need a little alter, as there are 2 child’s tickets.
The equation would be:
78 = 1/2 (x+2(x-6))
78×2 = (x+ 2x - 12)
156 = 3x-12
156+12 =3x
x = 168/3
x=56
As $56 is the price of an ticket for adult,the price of a child’s ticket would be:
56-6
=$50
Therefore the answer is A.$50
Hope it helps!
