Answer:
The equation to determine the number of days Margo has owned the plant is .
Step-by-step explanation:
Given:
Actual length of the tree = 5 cm
Current length of the tree = 65 cm
Per day growth Rate of plant = 2.5 cm
Let number of days she owned the plant be 'x'
Now We can say that,
Current length of the tree is equal to sum of Actual length of the tree and Per day growth Rate of plant multiplied by number of days she owned the plant.
Farming the above sentence in equation form we get;
Hence the equation to determine the number of days Margo has owned the plant is .
