Answer:
Erin made 5.5 dozen cookies.
Step-by-step explanation:
Total cookies made by Kim, Mary and Erin = 24 dozen cookies
Let Erin make cookies = x dozens
Mary made cookies = 2x dozens
Kim made cookies = x+2 dozens
Now, we need to find how many cookies did Erin made.
We can write:
Solving the equation we get:
So, Erin made cookies = x = 5.5 dozens
Mary made cookies = 2x =2(5.5) = 11 dozens
Kim made cookies = x+2 =5.5+2 = 7 dozens
Therefore, Erin made 5.5 dozen cookies.
Answer:
n=6.77 months (exactly)
n=7 months (nearest integer, less accurate)
Step-by-step explanation:
A) The initial number of bees in a colony is 1500. Each month the number of bees decreases by 12% which means each month we must factor by (1-0.12)=0.88
So the number of bees as a function of n months is
1500*0.88*0.88...0.88 (n times)
The initial number of flowering plants is 800 and there are 25 fewer of them each month. It can be written as
B) After 6 months (n=6) there will be
And there will be
flowering plants
C) We want to know the value of n that make B = P:
Rearranging
This equation cannot be solved by exact procedures, we must approach the answer or use any numerical method to solve for n
The best value to solve the equation is n = 6.77 months in which case
And flowering plants
If we wanted to use only integers for n, then we should use the nearest integer to our previous value, that is, n=7. In this case,
flowering plants
