10. Higher Order Thinking The ticket price for a concert at a historic music
hall includes $6.40 for the concert, $4.80 for the program, and a hall
restoration fee. The price for 11 tickets is $128.15.
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.

(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 = = $11.65

By the Equation, x +6.40+4.80 =11.65

                     or, x = 11.65 - 11.20

                          ∴ x = $ 0.45

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
