Luis wants to buy a skateboard that usually sells for $79.35. All merchandise is discounted by 12%. What is the total cost of the skateboard if Luis has to pay a state sales tax of 8.25%. Round your intermediate calculations and answer to the nearest cent

The total cost of the skateboard is 75.58881, rounded, it's $75.59.

Step-by-step explanation:

Since the merchandise is discounted by 12%, this means there's a decrease in price.

We need to convert our discount to a decimal, 0.12, and then multiply it by the original price. So,

$79.35 × 0.12 = 9.522

Then we subtract: $79.35 - 9.522 = 69.828

Since we have to pay a sales tax of 8.25%, we need to convert that into a decimal, 0.0825, and then multiply the sales tax by 69.828. So,

69.828 × 0.0825 = 5.76081

Now we add 5.76081 to our price, 69.828, which is 75.58881.  75.58881 rounded to the nearest hundredth is 75.59.

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
