Answer: 94 child tickets

<u>Step-by-step explanation:</u>

Let x represent child tickets

Let y represent adult tickets

Cost Equation: 5.70x + 9.75y = 1306.10

Quantity Equation: x + y = 173

Solve the system of equations using the elimination method:

Multiply the Quantity Equation by -5.70

      5.70x + 9.75y = 1306.10

    <u> -5.70x  - 5.70y</u> = <u>-986.10</u>

                    4.05y = 320.00

                  <u> ÷4.05 </u>   <u>÷4.05    </u>

                           y =   79

x +  y  = 173

x + 79 = 173

x         = 94

Why is it possible to have two different rational functions with the same asymptotes?
jolli1 [7]

Answer: Down below.

Step-by-step explanation:

A horizontal asymptote for a function is a horizontal line that the graph of the function approaches as x approaches ∞ (infinity) or -∞ (minus infinity). ... There are literally only two limits to look at, so that means there can only be at most two horizontal asymptotes for a given function
