A shopper wants to ensure he has enough cash to purchase a $33 encyclopedia, so he asks a clerk what the total will be with the sales tax included. The clerk tells him the total will be $34.65. What is the sales tax percentage?

My answer is .05 which is 5%. Am I correct?

First, divide with a calculator.

Now subtract , which is equivalent to the value of the item, as it is equal to .

Move the decimal two places to the right to convert it to a percentage.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
