a. Write an equation to represent the cost of the hall restoration fee,
b. Solve the equation to find the cost of the hall restoration fee.​

Respuesta :

Answer: (a) The equation to represent the cost of hall restoration fee will be ( x + 6.40 +4.80 = 11.65 )

(b) The cost of the hall restoration fee will be $0.45

Step-by-step explanation:

Let, The hall restoration fee for a single ticket = $ 'x'

Now, Concert fee is $6.40,

       Program fee is $4.80,

The price for 11 tickets is $128.15. So,

The ticket price for a single ticket is =[tex]$\frac{128.15}{11}[/tex] = $11.65

By the Equation, x +6.40+4.80 =11.65

                     or, x = 11.65 - 11.20

                          ∴ x = $ 0.45
