Explanation:
Step 1: Calculate per apartment;
⟼ 228,000 ÷ 24
⟼ 9,500
Step 2: Multiply the price per apartment by 10;
⟼ 9,500 × 10
⟼ 95,000
Step 3: Substract the amount of 10 apartments from 24 apartments.
⟼ 228,000 - 95,000
⟼ 133,000
Therefore, $133,000 is still available for the remaining apartments.
