  1. A car travels 480 km on 40 litres of fuel. What is the fuel efficiency in km/L?

    Answer: 12 km/L

    Fuel efficiency = 480 ÷ 40 = 12 km/L.

  2. A jacket originally costs $180. It is on sale for 35% off. What is the sale price?

    Answer: $117.00

    Discount = 35% of $180 = $63. Sale price = $180 − $63 = $117.

  3. What is the area of a rectangle with a length of 14 m and a width of 9 m?

    Answer: 126 m²

    Area of a rectangle = length × width = 14 × 9 = 126 m².

  4. A store sells 3 items for $7.50. How much would 8 items cost?

    Answer: $20.00

    Cost per item = $7.50 ÷ 3 = $2.50. Cost of 8 items = 8 × $2.50 = $20.00.

  5. A recipe requires 2.5 cups of flour per batch. How many cups of flour are needed for 4 batches?

    Answer: 10 cups

  6. A savings account earns 3% simple interest per year. If you deposit $2,000, how much interest will you earn after 2 years?

    Answer: $120

    Simple interest = Principal × Rate × Time = $2,000 × 0.03 × 2 = $120.
