Q. Astrid is in charge of building a new fleet of ships. Each ship requires xx tons of wood, and accommodates yy sailors. She receives a delivery of zz tons of wood each day. The deliveries can continue for nn days at most, afterwards the weather is too bad to allow them. Overall, she wants to build enough ships to accommodate at least mm sailors. How much wood does Astrid need to accommodate kk sailors?
  1. Identify Sailor Capacity: Identify the number of sailors each ship can accommodate. Let's say each ship accommodates SS sailors.
  2. Determine Total Sailors: Determine the total number of sailors Astrid wants to accommodate. Let's say she wants to accommodate TT sailors.
  3. Calculate Ships Needed: Calculate the number of ships needed. Number of ships needed = TS \frac{T}{S}
  4. Identify Wood Requirement: Identify the amount of wood required for each ship. Let's say each ship requires WW tons of wood.
  5. Calculate Total Wood: Calculate the total amount of wood needed. Total wood needed = Number of ships needed×W\text{Number of ships needed} \times W
  6. Simplify Expression: Simplify the expression. Total wood needed = TS \frac{T}{S} * W W
  7. Calculate Total Wood: Plug in the values and calculate. For example, if each ship accommodates 1010 sailors, and she wants to accommodate 100100 sailors, and each ship requires 55 tons of wood: Total wood needed = (10010)×5\left( \frac{100}{10} \right) \times 5 Total wood needed = 10×510 \times 5 Total wood needed = 5050 tons
