Answer:
(x) =
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 5x + 4 ( subtract 4 from both sides )
y - 4 = 5x ( divide both sides by 5 )
= x
change x to (x) and y back to x, thus
(x) =
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.
