Final answer:
To represent the situation where the amount of flour used by the bakery this month is a 40% increase relative to last month, you can use a bar graph. The x-axis represents the months, and the y-axis represents the amount of flour used.
Step-by-step explanation:
To represent the situation where the amount of flour used by the bakery this month is a 40% increase relative to last month, you can use a bar graph. The x-axis can represent the months, with the last month on the left and the current month on the right. The y-axis can represent the amount of flour used. On the graph, you can show the amount of flour used last month and the amount used this month, with the height of the bars representing the quantity of flour. The bar for this month should be 40% higher than the bar for last month.
