  1. A worker earns $22.50 per hour and works 37.5 hours per week. What are the worker's weekly gross earnings?

    Answer: $843.75

    Weekly earnings = $22.50 × 37.5 = $843.75.

  2. The temperature dropped from 4°C to −11°C overnight. By how many degrees did the temperature drop?

    Answer: 15°C

    Temperature change = 4°C − (−11°C) = 4 + 11 = 15°C.

  3. A container holds 3.75 litres of juice. If 6 people share it equally, approximately how much does each person receive?

    Answer: 0.63 L

    Amount per person = 3.75 ÷ 6 = 0.625 L ≈ 0.63 L.

  4. A room is 6.4 m long and 4.5 m wide. What is the perimeter of the room?

    Answer: 21.8 m

    Perimeter = 2 × (length + width) = 2 × (6.4 + 4.5) = 2 × 10.9 = 21.8 m.

  5. If a train travels at an average speed of 95 km/h, how long will it take to travel 380 km?

    Answer: 4 hours

    Time = Distance ÷ Speed = 380 ÷ 95 = 4 hours.

  6. A tax of 13% (HST) is applied to a purchase of $64.00. What is the total amount paid?

    Answer: $72.32

    Tax = 13% × $64.00 = $8.32. Total = $64.00 + $8.32 = $72.32.
