Ainsley made a $75 deposit to her savings account.what integer represents the deposit?
Dima020 [189]

In this case, Ainsley is <em>adding </em>money to her savings, so the $75 deposit could be represented as the <em>positive </em>integer 75.

The opposite, of course, would be if Ainsley <em>withdrew </em>that money from her savings. In that case, we'd be subtracting money from the account, so we could use the <em>negative </em>integer -75 to represent that scenario.
