The document describes 4 word problems involving calculating the cost of different flower purchases at a maths shop. In each problem, students are asked to calculate the total cost using the prices listed and number of flowers purchased. The solutions confirm the correct calculations and provide feedback to encourage using multiples of 10 to simplify the multiplication, such as calculating 12 x 49 as 12 x 50 - 12.
