A) $1,785
B) $1,855
C) $1,895

Write the correct answer on each line.
1. A contractor charges $1,250 per room. After painting 5 rooms and giving an $875 discount, the customer pays $5,375
Step 1: 5 × 1,250 = 6,250. Step 2: 6,250 − 875 = $5,375.
2. A factory produces 7,200 parts in 8 hours. At this rate, it makes 2,700 parts in 3 hours.
Step 1: 7,200 ÷ 8 = 900/hour. Step 2: 900 × 3 = 2,700 parts.
3. A store orders 4 TVs at $768 each. Shipping costs bring the total to $4,000. The shipping cost is $928
Step 1: 4 × 768 = 3,072. Step 2: 4,000 − 3,072 = $928 shipping.
4. A reservoir holds 9,500 liters split into 4 equal tanks. One tank is drained of 1,500 liters. That tank has 875 liters.
Step 1: 9,500 ÷ 4 = 2,375 liters per tank. Step 2: 2,375 − 1,500 = 875 liters.
5. Max buys 6 concert tickets at $345 each. He pays with $2,500. His change is $430
