Mike has some money in his account. Every month, he uses the same amount of money from his account to pay for his aerobics classes. The table below shows the amount of money left in his account after a certain amount of time, in months: What is the value of the rate of change of the function for this table and what does it represent in this situation? $50 per month; the initial amount of money in the account −$50 per month; the amount of money withdrawn per month −$280 per month; the amount of money withdrawn per month $280 per month; the initial amount of money in the account

The correct answer is -$50 per month; the amount of money withdrawn per month. From one month to the next, Mike loses 50 dollars from his bank account, presumably because he's withdrawing it. To find this, just subtract each number from the number below it. 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!
