What about item 4

Let's solve Item 4.

(a) Calculate the total cost of the items for each house.

We'll use the total number of items per house calculated previously and the cost per item.

• Pink House:

  • Balls: $19 \times 60,000 = 1,140,000$
  • Boxes of Water: $25 \times 12,000 = 300,000$
  • Kits: $27 \times 8,000 = 216,000$
  • Total Pink House Cost: $1,140,000 + 300,000 + 216,000 = 1,656,000$

• Blue House:

  • Balls: $15 \times 60,000 = 900,000$
  • Boxes of Water: $21 \times 12,000 = 252,000$
  • Kits: $24 \times 8,000 = 192,000$
  • Total Blue House Cost: $900,000 + 252,000 + 192,000 = 1,344,000$

• Red House:

  • Balls: $11 \times 60,000 = 660,000$
  • Boxes of Water: $18 \times 12,000 = 216,000$
  • Kits: $18 \times 8,000 = 144,000$
  • Total Red House Cost: $660,000 + 216,000 + 144,000 = 1,020,000$

(b) Calculate the total amount of money that will be requested for by the sports master.

This is the sum of the costs for each house.

Total Amount Requested = Total Pink House Cost + Total Blue House Cost + Total Red House Cost
Total Amount Requested = $1,656,000 + 1,344,000 + 1,020,000 = 4,020,000$

This matches the total cost calculated in Item 3(c).
