B^2 + b = 2
b^2 + b + 1/4 = 2 + 1/4
(b + 1/2)^2 = 9/4
b + 1/2 = (+-) sqrt 9/4
b + 1/2 = (+-) 3/2

b = -1/2 + 3/2 = 2/2 = 1
b = -1/2 - 3/2 = -4/2 = -2

12345 [234]

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

  • Substitute y = 1.5 into

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.
