Ответ:
230 - 280 = -50
180 - 230 = -50
130 - 180 = -50
Therefore, the rate of change is -50, because Mike loses $50 each month. This means that he withdraws $50 from his bank account each month.
Hope this helps!

Step-by-step explanation:
A gasoline cost $2.75 per gallon
A diesel cost $3.02 per gallon
15.2 gallons of gasoline will cost
15.2 * 2.75 =$41.8
9.5 gallons of diesel will cost
9.5 * 3.02= $28.69.
The total amont Grabiel will spend on gasoline and diesel =
$41.8 +28.69= $70.49
