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?

Answer 1

450=-3x

x=-150

If Leon uses 3 grams of tea leaves to make a cup of tea each morning, a container filled with 450 grams of tea leaves will last him approximately 150 days.

Answer 2

`y=450-3x`

Explanation:

We know that Leon has 450 grams of tea leaves in the container, this represent the initial condition, which is a value that will be subtracted constantly each morning, because each day Leon is gonna use 3 grams. So, let's represent days as x, the expression would be

`y=450-3x`

Where y represents the total amount of tea leaves remaining. As you can observe, there's expressed the difference between the initial condition (450 grams) and the daily consumption.
