1.caleb is buying a basketball that regularly costs $30. if the tax rate is 8%, what is the total price of the basketball including tax?

$32.40

Step-by-step explanation:

We must ADD 8% sales tax to the price of the basket ball. ($30.00)

But what is 8% of $30.00?

First we must convert 8% to a decimal.

To do that we move the existing invisible decimal two places to the left.

So in 8% the invisible decimal is here

8.0

_^

If we move it two places to the left then we have

. 8

^__

Always fill in the space(s) with 0.

.08 Is the same as 8%

So what is 8% of $30.00?

Well we have to multiply the price of the basketball by the percentage of sales tax.

30 × .08 = 2.4

Same as: $30.00 × 8% = $2.40

$2.40 is 8% of $30.00

Last, to find the total price including sales tax, we must ADD the sales tax to the price of the basketball.

$30.00 + $2.40 = $32.40

Hope this helps!

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
