Answer:
F = 100 + 0.1d
Step-by-step explanation:
- Initial charge is $100
- Price for climbing 3000 m = 400
<u>Then equation to find a fee per vertical distance:</u>
- 100+3000x = 400
- 3000x = 300
- x = 300/3000
- x = $0.1 per/m
So the fee for climbing vertical distance is $0.1 per meter.
- Vertical distance = d m
- Total cost = F
<u>Then, required equation is:</u>
Answer:
2(1)²−1= 1
2(2)²−1= 7
2(3)²−1= 17
2(4)²−1= 31
2(5)²−1= 49
