Lina's green pepper plant was 32.65 cm tall in June. During the months of July, August, and September the plant grew 2.6 cm every month. How tall was Lina's green pepper plant at the end of September?

40.45 cm

Step-by-step explanation:

Length of Lina's green pepper plant = 32.65 cm

It grows 2.6 cm during the months of July, August, and September.

Length at the end of July = 32.65 cm + 2.6 cm = 35.25  cm

Length at the end of August = 35.25  cm + 2.6 cm = 37.85  cm

Length at the end of September = 37.85 cm + 2.6 cm = 40.45 cm

So, its length will become 40.45 cm at the end of September.
