Olivia spent 78 dollars at a supermarket. If she has 33 dollars left with her how much money did she have initially?
First, we need to find out how much money Olivia spent. 78 dollars is the same as 78/1 dollars, so we can say that Olivia spent 78/1 dollars. 

Next, we need to find out how much money Olivia has left. 33 dollars is the same as 33/1 dollars, so we can say that Olivia has 33/1 dollars left. 

Now, we need to find out how much money Olivia had initially. We know that Olivia spent 78/1 dollars and she has 33/1 dollars left, so we can say that Olivia had 78/1 - 33/1 = 45/1 dollars initially. 

We can simplify 45/1 dollars to just 45 dollars, so we can say that Olivia had 45 dollars initially. 

Therefore the answer (numeric) is: 

45
