To determine the total change in the stand's bank account, we need to consider both the amount withdrawn and the amount deposited.
-
Lexi withdrew $150 from the account, which is a negative change: \[ -150 \]
-
Lexi deposited $437 into the account, which is a positive change: \[ +437 \]
Now, we combine these two amounts to find the total change: \[ \text{Total Change} = -150 + 437 \]
Calculating that gives: \[ -150 + 437 = 287 \]
Thus, the total change in the stand's bank account relative to where it started is \(\boxed{287}\) dollars.
