e-lub [12.9K]

Answer:

2.4 (2 2/5) pieces of pie per person.

Step-by-step explanation:

All that is needed to be done is simple division. Take your pieces of pie, (12) and divided it by the amount of people (5). This will give you 2.4. This can be turned into 24/10, and can be simplified twice. First to 12/5, then to 2 2/5.

Suppose the a mountain bike that sells for $419 is on sale for 20.5% off.
nata0808 [166]
Regular price:  $419
Sale price:  (1-0.205)($419) = $333.11

The bike will cost $333.11 before tax.  You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be 

(1.00 + rate as a decimal fraction)*$333.11.

Example:  If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).
