## here we have the value of input is distance and the output value is for the cost.

★ in case f(d) represent the fare function of distance.

★ then the function would be like this : -

f(d) = {8 , 8 + 1.5(d)}

here if 0 < d ≤ 4

when if d > 4

★here the notation d simplify the greatest integer applied to d.

★ the greatest integer ≤ to d

e.g : -

(4.1) = (4.9) = 4

79

step-by-step explanation:

x=63

y=16

x+y= destination

63+16=79

if you will travel back you just need to minus the miles you traveled to come back to the starting point
