Answer:
512000
Step-by-step explanation:
8*10
80*80*80
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
Given:
To find:
The recursive formula.
Solution:
We have,
It is in the form of explicate formula of a GP, .i.e., 
.
Here, 
and 
.
The recursive formula of a GP is
Using this the recursive formula for given problem is
Therefore, the required recursive formula is .
Answer:
i think its b. because you would line them up and you never subtract the denominator.
