Answer:
- 10 2/3 years or 10 years and 8 months
Step-by-step explanation:
Assumed it is a simple interest with rate r.
<u>Find the rate:</u>
- 4000(1 + 8r) = 5000
- 1 + 8r = 5000/4000
- 8r = 1/4
- r = 1/32
<u>Find the time for the second amount:</u>
- 2100(1 + 1/32t) = 2800
- 1 + 1/32t = 2800/2100
- 1 + 1/32t = 1 1/3
- 1/32t = 1/3
- t = 32/3
- t = 10 2/3

Based on the task content given; the initial fee and the fee per stop is $2 and $1.5 respectively.
<h3>Equation</h3>
let
- Initial fee = x
- Fee per stop = y
x + 3y = 6.50
x + 7y = 12.50
- Subtract both equation to eliminate x
7y - 3y = 12.50 - 6.50
4y = 6
y = 6/4
y = 1.5
x + 3y = 6.50
x + 3(1.5) = 6.50
x + 4.5 = 6.50
x = 6.50 - 4.5
x = 2
Therefore, the initial fee and the fee per stop is $2 and $1.5 respectively.
