Question

What is the answer to $30 dinner; 8% tax

Answer 1

$32.40

What is a percentage?

A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

To figure out what 8% of 30 is, we can use this equation:

• 0.08 × 30 = 2.4

Why do we multiply by 0.08?

Well, if we know that percentages are parts of 100, we can conclude that 8% =
`(8)/(100)` = 0.08.

Now that we know that the tax costs $2.40, we can add that to the price of the dinner.

• 30 + 2.4 = 32.4

Therefore, the price of the dinner including tax is $32.40
