And a standard deviation of
.After saving this money Jon plans to go on a trip to India.He will change his money into Rupees at an exchange rate of 43 Rupees to one Dollar.This money he will bring to India.When he arrives in India he will buy a used motorbike.The price in India of a motorbike of the type he wants is a random variable B with a mean of
Rupees and a standard deviation of
Rupees .
The amount of money Jon will have left (in Rupees) after changing his savings into Rupees and buying a motorbike in India is a random variable P which can be expressed in terms of S and B as P = 43S - B.
Find expressions for the mean and variance of the random variable P.Assume that Jon's savings and the price of the bike are independent.

• A)mean = 43 - ,variance = 1849 -
• B)mean = 43 - ,variance = 1849 +
• C)mean = 43 + ,variance = 1849 +
• D)mean = 43 + ,variance = 43 +
• E)mean = 43 - ,variance = 43 +
