Answer: $172.50
Step-by-step explanation: Method 1:
The original price of the item is $230.
The discount is 25%.
Let's find 25% of $230.
25% of $230 = 0.25 * $230 = $57.50
The discount amount is $57.50.
Now we subtract the amount of the discount from the original cost.
Sale price = $230 - $57.50 = $172.50
Method 2.
The original price is $230.
That means that $230 is 100% of the price since 100% of a thing means the entire thing.
Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%.
The sale price is 75% of the original price.
Now we find 75% of $230.
75% of $230 = 0.75 * $230 = $172.50
About $36
***
11.9 gallons, and $3.04 for each gallon. So, the price of a full tank is 11.9*3.04=36.176.
Since it said to estimate, you need to round the numbers. 12*3=36 will do.
Appreciation rate = 1.2% = 0.012
Let it take n years
300000^0.012n = 350000
taking log
0.012n * log(300000) = log(350000)
0.012n * 5.4771 = 5.5440
0.0657252 n = 5.5440
n = 84.35 years
2017 + 84.35 = 2101.35
It will be worth $350,000 in 2101

Step-by-step explanation:
1) probability for odd or 00 = (18+1)/38 = 0.5
2) expected value can be calculated as follows :
14 * win probability - 13 * lose probability
=14 * (18/38) - 13*(20/38)
= -0.21
