16x3=18
25x3=75
22-18=4
4km=19
19+75=94
Jawabannya 94. 000 menurut saya tapi koq ndak ada jawabnnya
pake persamaan garis yah
misalkan
y= tarif
x= jarak tempuh
m=y2-y1/x2-x1
m=19-13/4-2
m=6/2
m= 3
persamaan garis
y= m(x-x1)+y1
y=3(x-2)+13
y=3x-6+13
y=3x+7
x = 22
maka
y=3x+7
y=3(22)+7
y=66 + 7
y=73
jadi tarifnya Rp. 73.000.00 Option B
