Question

Dr. Adams measures the daily height of a Sunny Yellow sunflower, beginning when the sunflower is 60 days old. At 60 days old, the height is 205 centimeters. After the first 60 days, Dr. Adams find that the growth rate is 2 centimeters per day.

A: Write and expression for the height at d days past 60 days.

B: In how many days will the sunflower reach 235 centimeters?

C: The Suntracker sunflower grows 2.5 centimeters per day after the first 60 days. If a Suntracker is 195 centimeters tall when it is 60 days old, write an expression to represent the Suntracker's height d days after 60 days. Which sunflower will be taller when it is 82 days old? Explain how you found your answer.

Answer 1

A: the height grows 2 inches every day, so you would multiply 2 and d (number of days) and add 205 because that is its starting height when counting the days
so y= 2d+205
