Cameron and Casey go out to lunch. If their food and beverages cost a total of $22.50, and there is 9% meals tax, how much is the bill after the tax is added? Label your answer.

$24.525

Step-by-step explanation:

Given data

cost = $22.5

tax = 9%

Required

The amount of the tax2.025 and the cost of food together

Let us compute 9% of 22.5

=9/100*22.5

=0.09*22.5

=$2.025

Hence the bill is 22.5+2.025

=$24.525

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
