A seafood restaurant daims an increase of $2,450 over its average profit during a weer where it introduced a special of baked class.

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.
