<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:
The correct answer is the sales tax charged is $5.61 for $66 dinner at 8.5% tax rate.
Step-by-step explanation:
Cost of the dinner is $22. Tax levied on it is $1.87
Let x% is the rate of tax in the city.
Therefore, x% of 22 = 1.87
⇒ x = 1.87 × = 8.5
Therefore 8.5% is the tax rate in the city on foods.
Now another dinner costs $66.
Tax levied on it at the same percentage is given by 8.5% of 66 = $5.61.
Thus $5.61 as sales tax would be charged for a $66 dinner.
