Answer:
a. y = 250 (0.4)^x
b. 0.066
Step-by-step explanation:
The equation can be modeled as a geometric sequence, where the first term is 100 and the common ratio is 0.4.
y = 100 (0.4)^(x − 1)
This can also be simplified to:
y = 250 (0.4)^x
When x = 9:
y = 250 (0.4)^9
y = 0.066
I think the answer is $60
Answer: The number of steps you can make is 5 pieces and
is left over.
Step-by-step explanation:

Length of pieces from the board to make ladder steps for a tree fort = 
Length of board = 120 inch
Number of pieces from the board to make ladder steps for a tree fort is given by

Hence, the number of steps you can make is 5 pieces and
is left over.
