$124.50

Step-by-step explanation:

Given : The equation y = 4.75x + 20 gives the cost y of towing a car if the car is towed x miles.

Using substitution property , We substitute x= 22 in the above equation, we get

$y = 4.75(22) + 20\\\\\Rightarrow y=104.50+20=124.50$

Hence, According to the model, the best estimate of the cost for towing a car 22 miles = $124.50
