Question

Leon has a container filled with 450 grams of tea leaves. Each morning, he uses 3 grams to make a cup of tea.

Which expression can be used to represent the amount of tea leaves remaining after x days?
450 – 3x

Answer 1

The expression 450 – 3x can be used to represent the amount of tea leaves remaining after x days.

Each day, Leon uses 3 grams of tea leaves to make a cup of tea. Therefore, the amount of tea leaves remaining can be calculated by subtracting the amount used each day from the initial amount of tea leaves.

450 (initial amount of tea leaves) - 3x (amount used each day) = remaining amount of tea leaves after x days.

Therefore, the expression 450 – 3x can be used to represent the amount of tea leaves remaining after x days.
