  1. Many beaches have narrowed over time due to what?

    • Answer: beach erosion
  2. The cost of beach nourishment for a coastal area is estimated at $5 million. If this cost is to be shared equally among four neighboring towns, how much will each town contribute?

    • Answer: $1.25 million (since $5 million ÷ 4 = $1.25 million)
  3. The total cost (C) of flood damage repair is represented by the equation C=mx+b, where m is the cost per square meter of damage and x is the area of flood damage in square meters. If the cost per square meter is $50, and there is a fixed cost (b) of $10,000 for other miscellaneous expenses, what is the total cost for flood damage repair for an area of 200 square meters?

    • Total cost C = 50x + b
    • C = 50(200) + 10,000
    • C = 10,000 + 10,000
    • C = $20,000
    • Answer: $20,000
