<span>Given:
AB = x + 16
BC = 4x + 11
AC= 77
We can safely assume that,
AB + BC = AC
x + 16 + 4x + 11 = 77
5x + 27 = 77
5x = 77 - 27
5x = 50
x = </span>
x = 10
Hence,
AB = x + 16 = 10 + 16 = 26
Hence, proved.

Answer:
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 .
