7 0

Answer: 13

Step-by-step explanation:

If you remember the quadratic equation formula;

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

You can easily extract what is under the root to find the discriminant.

$b^2-4ac=?\\$

a = 3

b = 7

c = 3

$(7)^2-4(3)(3)\\49-36=13$

Cost Adult tickets = x

Cost Children's tickets = y

The total cost of ticket = C =

A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15

C = $21 × x + $15 × y

C = 21x + 15y

The total cost of 4 adult tickets and 3 children's tickets is calculated as:

C = 21 × 4 + 15 × 3

C = 84 + 45

C = $129
