Question

]7. A zucchini plant in Darnell’s garden was 13 centimeters tall when it was first planted. Since then, it has grown approximately 0.6 centimeter per day.
a. Write a rule to describe the function.
b. After how many days will the zucchini plant be 0.208 meter tall?

Answer 1

Let d be the number of days and h be the height

h = 13 + 0.6d

Answer: (a) h = 13 + 0.6d

Given height = 0.208m, find d:

0.208m = 20.8 cm

20.8 = 13 + 0.6d

0.6d = 20.8 - 13 = 7.8

d = 7.8 ÷ 0.6 = 13

Answer: (b) 13 days
