Final answer:
The statement regarding the savings account decreasing by $4.50 per withdrawal is true, as supported by the linear equation y = 1200 - 4.50x.
Step-by-step explanation:
The question asks if the statement 'The amount of money in a savings account decreases by about $4.50 per withdrawal on average.' is true given the equation y = 1200 - 4.50x, where y is the amount of money left in the account and x is the number of transactions. The equation indeed shows a linear relationship where each withdrawal (increase in x) results in a decrease of the money in the account by the same amount ($4.50). Therefore, the given equation supports the statement that each withdrawal reduces the account balance by $4.50, and the statement is true.
The question is asking about the relationship between the number of withdrawal fees and the amount of money in a savings account. The equation given is y = 1200 - 4.50x, where y represents the amount of money in the account and x represents the number of withdrawal fees. The equation shows that for every withdrawal fee, the amount of money in the account decreases by $4.50 on average. Therefore, the statement that the amount of money in a savings account decreases by about $4.50 per withdrawal on average is True.
