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? a. 450 – 3x b. 450 + 3x c. 3 + 450x d. 3 – 450x

Your answer would be A. 450 - 3x

The reason being is that you start with 450 so that is your starting point. But he uses 3 a day so you would want to multiply the number of days (X) by three to find out how many leaves he used. The to find out the remaining number you would want to take that product and subtract it from 450.
