Answer:
D.)
15040000 <= k <=19840000
Step-by-step explanation:
V = 1200 -0.00002k
Value V after one year falls in the range of $803.20 and $899.20.
Let's substract these values from 1200.
1200-803.20=396.80
1200-899.20=300.80
So it means that
0.00002k= 396.80
And
0.00002k= 300.80
So
0.00002k= 396.80
K= 396.80/0.00002
K= 19840000
And
0.00002k= 300.80
K = 300.80/0.00002
K= 15040000
So range is between
15040000 <= k <=19840000
Answer:

Step-by-step explanation:

Step 1: Divide the numbers

Step 2: Simplify

Step 3: Simplify

Therefore, the simplified answer is 
Answer: let the common multiple be x..
according to given condition,
2x + x +x =36
4x = 9
Peter = 2x = 2 ×9 = £18
Gordon = Gavin = x = £9
Hope this helps have a amazing day bye!
