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, f b. solve equation to find the cost of the hall restoration fee

Equation for cost of the hall restoration fee 70.4 + 52.8 + 11f = 128 .15 and the cost of the hall restoration fee is $0.45 .

Step-by-step explanation:

Let us assume that the  hall restoration fee be f .

As given

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 .

Than the equation becomes

(Cost for concert + Cost for program + Hall restoration fee) × Number of tickets = Total amount of 11 tickets

Putting all the values in the above

(6.40 + 4.80 + f) × 11 = 128.15

Open the bracket

6.40 × 11 + 4.80 × 11 + 11f = 128.15

70.4 + 52.8 + 11f = 128 .15

11f = 128 .15 - 123.2

11f = 4.95

f = $ 0.45

Therefore the equation for cost of the hall restoration fee 70.4 + 52.8 + 11f = 128 .15 and the cost of the hall restoration fee is $0.45 .
