A factory building is located in an area subject to occasional flooding by a nearby river. You have been

brought in as a consultant to determine whether flood proofing of the building is economically justified.

The alternatives are as follows:

A. Do nothing. Damage in a moderate flood is $10,000 and in a severe flood, $25,000.

B. Alter the factory building at a cost of $15,000 to withstand moderate flooding without damage

and to withstand severe flooding with $10,000 damages.

C. Alter the factory building at a cost of $20,000 to withstand a severe flood without damage.

In any year the probability of flooding is as follows: 0.70, no flooding of the river; 0.20, moderate flooding;

and 0.10, severe flooding. If interest is 15% and a 15-year analysis period is used, what do you

recommend?

A man on an island 12 mi. south of a straight beach wishes to reach a point on shore 29 mi. east. If a motorboat, making 20 mi. per hr., can be hired at the rate of $2.00 per hr. for the time it is actually used, and the cost of land transportation is $0.06 per mi., how much must he pay for the trip.
