Answer:
B (22%) is the answer.
Skills needed: Financial Math, Percentage Computations
Step-by-step explanation:
1) First, let's calculate the cost of the extended warranty. That would be the new price minus the old price.
- This is due to the fact that the new price is phone + warranty, while the old price is just the phone.
- So [tex]\text{new price } - \text{old price} = 289-225=64[/tex]...warranty=64$
2) The warranty is 64 dollars. To find out what percent of the cost it takes up, we do [tex]\frac{warranty}{totalprice}[/tex] --> In this case, the [tex]totalprice[/tex] is the new price, since the warranty is included in this price.
- Our fraction would be: [tex]\frac{64}{289}[/tex]
- Divide this out, you get a decimal of: 0.2214...
- To get a percent, multiply by the decimal by 100, and it is [tex]22.14[/tex]%
22.14 rounds to 22, so 22% is the answer, and that is b.
