Question

elva monitors her savings account online. on monday she withdraws money, and the change to her account balance is $-51.25$. on tuesday she deposits money and the change to her balance is $+39.50$. she wants to know the total change in her account after the two transactions. you found that the total change in elvas account balance is about $-10$. what is the exact change to elvas account balance, in dollars? $-51.25 + 39.50 = square$

Explanation:

Step1: Identify the operation

We need to add the two changes to the account balance: \(-51.25\) (withdrawal) and \(+39.50\) (deposit). So the operation is \(-51.25 + 39.50\).

Step2: Perform the addition

To add these two numbers, we can rewrite it as \(39.50 - 51.25\) (since adding a negative is the same as subtracting the positive).

First, align the decimal points:

But since \(39.50 < 51.25\), the result will be negative. So \(39.50 - 51.25 = -11.75\).

Answer:

\(-11.75\)
