There were 39 dollars in Olivia's wallet. She collected 26 more dollars from an atm. After she visited a supermarket there were 12 dollars left. How much more money did she spend at the supermarket than she collected at the atm?
Olivia had 39 dollars in her wallet. 
She collected 26 more dollars from an ATM. 
That means she had a total of 65 dollars. 
After she visited the supermarket, she had 12 dollars left. 
That means she spent 53 dollars at the supermarket. 

To answer the question, we need to find out how much more money she spent at the supermarket than she collected at the ATM. We can do this by subtracting the amount she collected at the ATM from the amount she spent at the supermarket: 

53 (amount spent at supermarket) - 26 (amount collected at ATM) = 27

Olivia spent 27 more dollars at the supermarket than she collected at the ATM.
