Answer:

Our expression is 205+2d where d is days past 60.

Step-by-step explanation:

Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.

205

Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:

205+2

Day 62 will be:

205 +2+2

Notice, that for two days past 60, the sunflower has grown 2 times as much.

Our expression is 205+2d where d is days past 60.
