There were 3 dollars in Olivia's wallet. She collected 49 more dollars from an atm. After she visited a supermarket there were 49 dollars left. How much more money did she collect at the atm than she spent at the supermarket?
f we start with what we know, we know that she withdrew $100 from the ATM and spent $75 at the supermarket. So we're looking for how much more money she collected than she spent. We can find that by subtracting what she spent ($75) from what she collected ($100). So she collected $25 more than she spent.
