We are given

where
y is the cost in dollars
x is distance in dollars
now, we can find derivative



so,

So,
the rate of change of the cost in dollars with respect to the number of miles is 1.5.........Answer
(8x-10)°+(6x)°+(10x+10)°=360°
8x-10+6x+10x+10=360
8x+6x+10x-10+10=360
24x-10+10=360
24x=360
24x/24=360/24
x=15
