I would use algebra to solve this:
let the amount of child ticket sold be x and the amount of adults ticket sold be 2x
so 2x•9.60+ x•6.30 = 969.00
19.2x+6.30x = 969.00
25.5 x =969.00
x=38
hence ans is 38
an alternative solution would be:
9.60×2 + 6.30 = 25.5
969.00÷25.5= 38
the methods are actually almost the same.

As per given in question, T is mid - point of QP ; so the measures QT and TP are equal.
that is :
![\qquad \sf \dashrightarrow \: 2x + 1 = 3x - 5](https://tex.z-dn.net/?f=%20%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3A%202x%20%2B%201%20%3D%203x%20-%205)
![\qquad \sf \dashrightarrow \: 3x - 2x = 1 + 5](https://tex.z-dn.net/?f=%20%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3A%203x%20-%202x%20%3D%201%20%2B%205)
![\qquad \sf \dashrightarrow \: x = 6](https://tex.z-dn.net/?f=%20%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3A%20x%20%3D%206)
Value of x is 6, so correct choice is D
So subtract 55 from 35
35 - 55 = -20
then, put -20 over 55
-20/55 equals -0.36 repeating, rounded to -0.36, which equals 36%
the negative stands for decrease, so it's around 36% decrease
They All are moved 3 points right visible from (x-3) , The graph is one point up. It is a parabola means [ a(x-x0)^2 - D/4a ]. This is the formula. D is Discriminate. x0 (BUT NOT - x0) is the x coordinate of focus and (-D/4a) is the Biggest or smallest value of graph. that is y.
if a > 0 then we have smallest value y if a< 0 then we have biggest value y. Logically if The given y is greater than focus y0 coordinate then a can't be smaller than 0. a > 0 for sure. now we have 1 or 3 . so Logically the distance from y=5 should be 1. Sorry for bad answer. Hope that helps you.
