Explanation Given Information: The expression is, “ $ 56 decreased by 10 1 2 % ”. Consider that the original value or the base is $ 56 and rate of decrease is 10 1 2 % . As the rate of change is a decrease, so subtract that change from 100 % so as to compute the rate, R = 100 % − 10.5 % = 89.5 % Here, portion is missing. The formula to compute portion is P = B × R Compute portion by substituting B = 56 and R = 89

The college hiking club is having a fundraiser to buy new equipment for fall and winter outings. The club is selling Chinese fortune cookies at a price of $2 per cookie. Each cookie contains a piece of paper with a different number written on it. A random drawing will determine which number is the winner of a dinner for two at a local Chinese restaurant. The dinner is valued at $32. Since fortune cookies are donated to the club, we can ignore the cost of the cookies. The club sold 718 cookies before the drawing. Lisa bought 13 cookies. Lisa's expected earnings can be found by multiplying the value of the dinner by the probability that she will win. What are Lisa's expected earnings? Round your answer to the nearest cent.

The Honolulu Advertiser stated that in Honolulu there was an average of 659 burglaries per 400,000 households in a given year. In the Kohola Drive neighborhood there are 321 homes.
