159.98 divided by 6 is 26.66, hopefully this is correct...
Step-by-step explanation:
Continuous exponential growth model:
Where α is the growth rate parameter.
So if t is the starting point and t+t1 is the point that population is doubled:
So:
And as a result, t1, the time needed for the population to double at ANY given point is equal to:
We have been given that a pound of fertilizer covers 42 square feet lawn and we are asked to find amount of fertilizer to cover lawn which measures 6019.3 square feet.
To find the amount of fertilizer needed to cover the lawn we will divide the area of lawn by area covered by one pound of fertilizer.
Therefore, the amount of fertilizer that Vivian needs to buy would be 143.3 pounds.
