The business is taxed15thousanddollars on its first$50 thousandin sales, then35% of each increment of$10 thousandthereafter, up to$100 thousand.The amount taxed is given by the piecewise defined function

F(x) =

15,		x= 0, 10,, 50
2.5+0.35x,		x= 60, 70,, 100

wherexrepresents the receipts for the business and

F(x)

represents the sales tax, both in thousands of dollars.Evaluate

F(20).

F(20) =

Interpret the result.The value

F(20)

is the ---Select--- total of the receipts for the business total sales tax for the business in thousands of dollars when the ---Select--- total of the receipts for the business total sales tax for the business is thousand dollars.
